This page lists current and past '''bugs''' in ''Hearthstone'', minor or major errors within the game which cause deviations from intended behaviour.
+
'''Bugs''' are minor or major errors within ''[[Hearthstone]]'' which cause deviations from intended behaviour.
   
  +
The list of bugs in ''Hearthstone'' is too extensive and complex to list here. However, a comprehensive documentation of all current bugs can be found at '''https://github.com/HearthSim/hs-bugs''' Individual bugs are sometimes also mentioned on individual card or encounter pages.
''Note to editors: Bugs should only be added to the list if they can be verified by multiple people/sources with screenshot or video proof that the bug still exists as of the latest ''Hearthstone'' [[patch]]. Any observed sequence of events that does not match what official sources state should happen is considered a bug.''
 
   
  +
Bugs can be reported on [http://us.battle.net/forums/en/hearthstone/index the official forums].

===Non-gameplay bugs===
 
 
====AI deck selection flyout====
 
{{lv|Patch 4.0.0.10833|LoE patch}}
 
Click [[Solo Adventures]], click on "Practice", click "Choose" and pick a [[Deck]]. Then click these 3 buttons ''quickly'' in succession: "Back" button, "Choose" button and then the incoming "Choose" button. The AI deck selection flyout no longer shows up until you click "Back" and allow the whole deck selection menu to fully animate out before clicking the "Choose" button.

====Arena rewards====
 
{{lv|Patch 3.0.0.9786|TGT patch}}
 
You can open your [[Arena]] rewards alternatively with number keys (1-5). But if you manage to press the keys before the animation is finished, your reward will overlap with the packed box.

====Blurry game====
 
{{lv|Patch 4.0.0.10833|LoE patch}}
 
In your [[Collection]], if you right click on a [[Card back]] or a [[Hero]] and click the "Back" button in a quick succession, the game will become blurry.

====Deck Limit of 2 for Legendary cards====
 
{{lv|Patch 4.0.0.10833|LoE patch}}
 
"Deck Limit: 2" is sometimes displayed incorrectly for Legendary cards in the Collection Manager while constructing a deck. It is currently unknown what causes the bug.

====Decks ordered incorrectly====
 
{{lv|Patch 3.0.0.9786|TGT patch}}
 
Sometimes if you quit the game and go back to [[My Collection]], your [[Deck]]s will be ordered incorrectly.
 
* https://www.reddit.com/r/hearthstone/comments/3a13mv/quit_reordering_my_decks/
 
 
====Enlarged card====
 
{{lv|Patch 4.0.0.10833|LoE patch}}
 
You can make a big copy of a card linger on-screen in the [[My Collection]] screen if you drag and drop a card from your collection into your deck, on the collection screen. Doing this makes an overlay of the card, overlapping the current position, that doesn't move even when you change screens, until you exit the collection or mouse outside the window. If you right click a card, behind the right click screen, the card turns very big.

====Golden Alternate heroes====
 
{{lv|Patch 2.8.0.9554|TGT pre-purchase patch}}
 
If you have one of the new [[Alternate hero]]es golden ([[Alleria Windrunner]], [[Magni Bronzebeard]], [[Medivh]]), the border around their hero power is not golden when you enter a lobby of any of the play modes.
 
* http://www.reddit.com/r/hearthstone/comments/3c09gk/finally_reached_500_wins_with_medivh_no_golden/
 
* http://www.reddit.com/r/hearthstone/comments/3a25sc/golden_medivh_bug/
 
 
Similarly, when you enter the game, the area surrounding the hero (aka hero tray) is not golden.

====Golden Fan of Knives====

====Hidden Quest buffer====
 
{{lv|Patch 4.0.0.10833|LoE patch}}
 
If you don't complete your [[Quest]]s for 6 days and don't use the reroll function on them, you can store up to 3 quests in the hidden buffer, making it 6 quests in total.
 
* https://www.reddit.com/r/hearthstone/comments/3t9wx3/2_tips_that_i_never_see_anyone_mention_that_are/cx4ma95?context=100

* https://twitter.com/bdbrode/status/667049642484363264
 
 
====In-game gold====
 
{{lv|Patch 4.0.0.10833|LoE patch}}
 
When you start the game, your gold won't be shown to you until you go to a sub-menu and return back to the main menu.
 
* https://www.reddit.com/r/hearthstone/comments/3sazae/gold_doesnt_show_up_when_you_start_the_game/
 
 
====Old Murk-Eye/Captain's Parrot====
 
{{lv|Patch 4.0.0.10833|LoE patch}}
 
After you receive [[Old Murk-Eye]] or [[Captain's Parrot]] as a reward for having all [[Murloc]]s/[[Pirate]]s and go to your collection, they can appear there multiple times. This is purely a visual bug and can be fixed by restarting the [[Hearthstone]] client.

* https://www.reddit.com/r/hearthstone/comments/3a2z5l/golden_murk_eye_bug/

====Pandaria board (water)====
 
{{lv|Patch 3.1.0.10357|Mech War Tavern Brawl patch}}
 
On the Pandaria playing board, the water that flows to the plants flows forever without regrowing any plants. It happens on monitors with a refresh rate of 144Hz.

====Quest pop-up====

===AI bugs===
 
 
====AI killing its own minions====
 
 
[[General Drakkisath]]'s AI has been noted to use [[Drakkisath's Command]] on its own [[Kidnapper]].

====AI returning its own minions to their hand====
 
 
AI has been noted to return a newly played minion back to its hand with [[Youthful Brewmaster]] (Druid AI) or [[Kidnapper]] ([[General Drakkisath]]).
 
 
====Kel'Thuzad====
 
{{lv|Patch 4.0.0.10833|LoE patch}}
 
If the player controls a [[Kel'Thuzad]] and has any [[Taunt]] minions, the AI will stop attacking with its minions, mistakenly thinking that any Taunt minions it kills will just resurrect at the end of turn. This can be used to defeat most AI and [[Adventure]] bosses.
 
 
* https://twitter.com/bdbrode/status/596878031999774720
 
 
====Majordomo Executus (encounter)====
 
When in the [[Ragnaros the Firelord (boss)|Ragnaros]] phase of the boss battle, Ragnaros may bug out and refuse to use his [[Hero Power]] completely, even if the player has a lot of minions and he has sufficient mana left.
 
* http://us.battle.net/hearthstone/en/forum/topic/16953425543
 
 
===Adventures gameplay===
 
 
====Demolisher and Kel'Thuzad (encounter)====
 
{{lv|Patch 4.0.0.10833|LoE patch}}
 
If dealing 2 damage at start of your turn causes [[Kel'Thuzad (hero)|Kel'Thuzad]] to enter Phase 2 by lowering his Armor to 0, his turn immediately starts instead, plays out to completion, followed by the game ending in a draw.

====Firesworn====
 
{{lv|Patch 4.0.0.10833|LoE patch}}
 
In the [[Garr]] encounter, the [[Deathrattle]] of [[Firesworn]] does not count the death of any enemy Firesworns that have died earlier in the turn. It only counts friendly ones.

====Jaws====
 
{{lv|Patch 4.0.0.10833|LoE patch}}
 
In the [[Gluth]] encounter, Gluth uses a weapon called Jaws ([[Jaws (Normal)|Normal]]/[[Jaws (Heroic)|Heroic]]). When a minion with Deathrattle gets silenced and then dies, it still triggers Jaws. This is inconsistent with the fact that [[Scarlet Purifier]] and [[Lil' Exorcist]] both do not count nor trigger on minions with Deathrattle that are silenced.

* http://www.mmo-champion.com/threads/1705138-Gluth-in-Naxx?p=32213902
 
 
====Massive Runeblade (Heroic)====
 
{{lv|Patch 4.0.0.10833|LoE patch}}
 
In the [[Instructor Razuvious]] encounter, [[Massive Runeblade (Heroic)|Massive Runeblade]] does not actually do double damage to Heroes as stated on the card text if it was equipped prior to aura effects, such as [[Spiteful Smith]]'s [[Enrage]]. The weapon simply deals additional damage equal to its base Attack, so the Runeblade will deal 22 damage instead of 24. This does not happen in normal difficulty, where the [[Massive Runeblade (Normal)|Runeblade]] is working correctly.

====Moira Bronzebeard and Immune hero====
 
{{lv|Patch 4.0.0.10833|LoE patch}}
 
If your hero is [[Immune]] and you have no minions with [[Taunt]] on the board during the [[Emperor Thaurissan (boss)| Emperor Thaurissan]] encounter, Moira Bronzebeard ([[Moira Bronzebeard (Normal)|Normal]]/[[Moira Bronzebeard (Heroic)|Heroic]]) will instead choose to attack into one of the minions and potentially die. This contradicts her card text that she will never attack minions unless they have Taunt.
 
* http://www.reddit.com/r/hearthstone/comments/31nhe6/interesting_interaction_in_the_emperor_thaurissan/
 
* https://www.youtube.com/watch?v=noNF0Oqz544
 
 
If there are no valid targets for Moira to attack (every target including the hero is Immune or has Stealth), Moira will not attack anything.
 
* https://www.youtube.com/watch?v=gJVgjDsVwF8
 
 
====Nefarian (encounter)====
 
{{lv|Patch 4.0.0.10833|LoE patch}}
 
If you deal enough damage to break his armor and kill [[Nefarian (Hidden Laboratory)|Nefarian]] in Phase 1 in a single hit, the battle immediately ends in victory and skips Phase 2 and Phase 3 of the encounter. This is probably because Nefarian is the same entity/character in both Phase 1 and 3, so killing him ends the encounter directly. This bug exists on both Normal and Heroic difficulties.
 
* http://www.reddit.com/r/hearthstone/comments/34fjjf/psa_you_can_skip_the_entire_second_and_third
 
 
====Siege Engine and Ragnaros====
 
{{lv|Patch 3.0.0.9786|TGT patch}}
 
When [[Majordomo Executus (boss)|Majordomo Executus]] is killed and [[Ragnaros the Firelord (boss)|Ragnaros]] is summoned for the next phase of the fight, if Majordomo controls a [[Siege Engine]], the game hangs. The player does not see Steam Engine trigger (Ragnaros gains 8 [[Armor]] after entering play) until the player restarts Hearthstone and reconnects to the game.
 
 
===Golden card bugs===
 
 
====Animations on card art====
 
{{lv|Patch 3.1.0.10357|Mech War Tavern Brawl patch}}
 
Blizzard confirmed that the animations on some golden cards (on the card art, not the animations when you play the card) are bugged with missing layers and/or animations since [[Patch 2.7.0.9166]] (Tavern Brawl patch). Affected cards are golden [[Gul'dan]]. There are possibly other affected cards and heroes not listed here.

* http://us.battle.net/hearthstone/en/forum/topic/18596060319
 
 
Golden [[Rexxar]] was also bugged, but (only) Rexxar was fixed in [[Patch 2.8.0.9554]].
 
* https://www.reddit.com/r/hearthstone/comments/39z2fu/golden_rexxar_hunter_portrait_has_been_stealth/
 
 
[[Dread Infernal]], [[Blizzard]], [[Neptulon]], [[Ragnaros the Firelord]], and [[Guardian of Kings]] were also affected by this bug but as of [[Patch 3.1.0.10357]] these cards were fixed. Video proof of this can be seen below.
 
* Dread Infernal https://www.youtube.com/watch?v=efocqnBSCHE
 
* Blizzard https://www.youtube.com/watch?v=_Y8N8YwEV28

* Guardian of Kings https://www.youtube.com/watch?v=RQaNp-H5NUM
 
 
====Transform/create/copy Effects====
 
{{lv|Patch 4.0.0.10833|LoE patch}}
 
Currently the behavior used by regular cards that create, transform or copy cards on [[Golden]] minions can be inconsistent. Ben Brode responded with: "Most of the things you've brought up are bugs", however it's not clear which specifically are bugs and which don't. Here is the list of current interactions of regular cards used on golden minions and whether the resulting minion is regular or golden.
 
* [[Mirror Entity]] -> Golden
 
* [[Chromaggus]] -> Golden
 
* [[Polymorph]] -> Golden
 
* [[Tinkmaster Overspark]] -> Golden
 
* [[Recombobulator]] -> Golden
 
* [[Gang Up]] -> Golden
 
 
* [[Imp-losion]] -> Golden [[Imp (Imp-losion)|Imp]]s
 
* [[Bane of Doom]] -> Golden [[Demon]]
 
 
* [[Faceless Manipulator]] -> Regular
 
 
Imp-losion (and possibly Bane of Doom) spawning golden minions were already considered a bug by Ben Brode:
 
 
https://twitter.com/bdbrode/status/574250317405007873
 
 
====Nerubian====
 
{{lv|Patch 4.0.0.10833|LoE patch}}
 
Golden [[Nerubian_(Grand_Tournament)|Nerubian]]s from [[Beneath the Grounds]]/[[Anub'arak]] have no golden animation
 
* https://www.reddit.com/r/hearthstone/comments/3orf38/golden_nerubians_from_beneath_the_grounds_have_no/
 
* https://imgur.com/Xx9bi33 (Beneath the Grounds)
 
* https://imgur.com/JvpnlY3 (Anubarak - Ben Brode confirms bug here)
 
(Both images above from the Reddit thread)
 
 
This issue does not affect golden [[Nerubian Egg]]s, as the 4/4 [[Nerubian_(Nerubian_Egg)|Nerubian]] from it is a different card (FP1_007t, Rare card, with [[Curse_of_Naxxramas|Naxxramas]] emboss in the background). The affected card is AT_036t, a [[The Grand Tournament|TGT]] card with no Gem on the card, with TGT emboss in the background.
 
 
===Audio-related gameplay bugs===
 
 
====Arena key====
 
{{lv|Patch 2.7.0.9166|Tavern Brawl patch}}
 
The sound effect of upgrading an [[Arena]] key after a win is not synchronized with the visual effects.
 
* http://www.reddit.com/r/hearthstone/comments/2d5t4l/the_sound_of_an_arena_key_upgrading_doesnt_sync/
 
* http://www.twitch.tv/nl_kripp/v/7058190&t=60m30s
 
 
====Button sound in background====
 
{{lv|Patch 4.0.0.10833|LoE patch}}
 
If you enable the "Sound in Background" option and switch to other programs such that their windows are overlaid over the [[Hearthstone: Heroes of Warcraft|Hearthstone]] window in the background, when you move your mouse inside the non-Hearthstone window over the locations of where Hearthstone UI buttons are, you can still hear UI button sound effects as though the active non-Hearthstone program window is not present.
 
* http://us.battle.net/hearthstone/en/forum/topic/12033553477
 
* https://www.youtube.com/watch?v=WDWvCeESM84
 
 
====Loud Sound Effects====
 
{{lv|Patch 4.0.0.10833|LoE patch}}
 
Sound effects scale with number of actors, making them much louder in some cases. This bug was introduced in Patch 4.0. It happens with multiple card effects.

More cards: Unleash the Hounds, Mukla's Champion.
 
 
====Missing play sound of minions====
 
{{lv|Patch 4.0.0.10833|LoE patch}}
 
If you use [[Faceless Manipulator]] on one of the minions, return the new minion back to your hand and then replay the minion again, his play sound will be missing. Same bug happens if you damage [[Grim Patron]] and return the new one back to your hand and then replay it again.

====Missing sounds of adventure minions====
 
{{lv|Patch 4.0.0.10833|LoE patch}}
 
Several [[adventure]]-only minions lack various sound effects.

====Weapon sound====
 
{{lv|Patch 3.1.0.10357|Mech War Tavern Brawl patch}}
 
The sound of equipping a [[Weapon]] is much quieter than expected.

===Spectator bugs===
 
 
====Slow motion====
 
{{lv|Patch 2.7.0.9166|Tavern Brawl patch}}
 
If you enter or exit [[Spectator mode]] while a hero's portrait is exploding in slow motion (in a match), Unity's Time.timescale (or otherwise) is not reset properly, causing the game to remain in slow motion until the game client is restarted.

====Spectating a Tutorial game====
 
{{lv|Patch 3.2.0.10604|2015-10-20}}
 
When a player spectates a win vs [[Illidan Stormrage (boss)|Illidan (tutorial)]], the win is broadcasted for their friend list as well.
 
 
===Tavern Brawl bugs===
 
 
====Annoy-o-tron (boss)====
 
{{lv|Patch 3.1.0.10357|Mech War Tavern Brawl patch}}
 
[[Annoy-o-Tron (Tavern Brawl)|Annoy-o-Tron]]'s Hero Power in [[Tavern Brawl]] does not give [[Taunt]]/[[Divine Shield]] to "negative" Attack minions.

====Core Hound Pup====

====Animations and sound effects playing multiple times====
 
{{lv|Patch 4.0.0.10833|LoE patch}}
 
If your action ([[Spell]] or [[Hero Power]]) gets interrupted by a minion trigger, its animation will play multiple times. Some of the exampes are listed below:
 
 
If you play [[Sacrificial Pact]] while having [[Auchenai Soulpriest]] and [[Floating Watcher]] in play, its animation will play twice.
 
* https://www.youtube.com/watch?v=OLslvNKyHEk&t=2m
 
 
If you use [[Armor Up!]] or play [[Shield Block]] while having [[Siege Engine]] in play, their animation will play twice.
 
* http://www.reddit.com/r/hearthstone/comments/3hb803/magni_siege_engine_causes_double_hero_power/
 
 
If you play spells, such as [[Dark Wispers]] or [[Unleash the Hounds]] while having [[Knife Juggler]] in play, their animation will play multiple times.
 
* https://www.reddit.com/r/hearthstone/comments/3har11/til_playing_knife_juggler_and_then_dark_wispers/
 
 
If you play [[area of effect]] spells, such as [[Lightbomb]] or [[Avenging Wrath]] while having [[Acolyte of Pain]] or [[Frothing Berserker]] in play, their animation will play multiple times.
 
* https://www.youtube.com/watch?v=b4wgGiAilto&t=11m05s
 
 
The sound effect of [[Lord Jaraxxus|Jaraxxus']] [[INFERNO!]] plays again for each [[Knife Juggler]] that triggers on Inferno's summon. Both players in the game can hear this bug.

When an opponent attacks with [[Truesilver Champion]], his portrait visibly lifts off the board twice, once before the healing trigger and once after it.
 
* https://www.youtube.com/watch?v=ClJfdopzsU8
 
 
If [[Nat Pagle]] triggers at the start of turn and draws into a [[Flame Leviathan]] or [[Fatigue]] damage, Nat Pagle's lightning icon visibly triggers but is interrupted by Flame Leviathan dealing 2 damage to all minions (or the Fatigue Damage animation), followed by Nat Pagle's lightning icon visibly triggering again, drawing another card. The second draw is actually the normal draw for the turn, so this bug is only visual in that Nat Pagle should not have visibly triggered a second time<sup>[Tested by Adys, Fisker and Xinhuan]</sup>.

If [[Anub'ar Ambusher]] dies to [[Explosive Trap]], and its [[Deathrattle]] tries to return the surviving attacking minion (that triggered the trap) to your hand, the minion will appear glitched out on the playing field. If you click on the empty space where the returned card should be, the card will appear back in your hand.

====Anub'arak====
 
{{lv|Patch 3.2.0.10604|2015-10-20}}
 
If you double click on [[Anub'arak]] after he takes fatal damage but before his [[Deathrattle]] fully animates, he may remain visually stuck on the board. If he does, then all minions that engage in attack will not correctly move back to their starting locations, and minions can be placed visually anywhere on the board. In addition, the Anub'arak minion that died may remain visually stuck in your hand.

====Attack value multiplied before death====
 
{{lv|Patch 4.0.0.10833|LoE patch}}
 
If [[Sacrificial Pact]] is used on [[Lord Jaraxxus|Jaraxxus]], his attack value visually changes from 3 to 9 and then 24 for a brief moment before he dies. If his attack is X, it changes to X*3 then to X*8 (tested with [[Spiteful Smith]] or [[Truesilver Champion]]).
 
* https://www.youtube.com/watch?v=gl529WTyJd4&t=1m6s
 
 
A similar bug can be reproduced by playing [[Bite]] or [[Heroic Strike]] and then dying.

Sometimes, the created cards have incorrect text. There have been reports of this happening to spectators, as well to players. It's possible it has to do something with reconnecting.

{{lv|Patch 4.0.0.10833|LoE patch}}
 
If a minion that does not normally have them is granted [[Divine Shield]] and or [[Taunt]], bounced to the hand (such as by [[Youthful Brewmaster]] or [[Sap]]) and replayed, it may erroneously display the visual effect of having Divine Shield/Taunt. It does not actually have them, and gameplay proceeds normally.

If you play [[Twisting Nether]] with [[Dreadsteed]]s on the board, the Dreadsteed [[Deathrattle]] animation will play at the wrong angles, sometimes being completely invisible, other times clipping through the camera.

====Forgotten Torch====
 
{{lv|Patch 4.0.0.10833|LoE patch}}
 
If you play [[Forgotten Torch]], the created card [[Roaring Torch]] is not visibly shuffled into the deck. There is no animation for it, giving the impression that the card is not created.

====Gladiator's Longbow====
 
{{lv|Patch 2.7.0.9166|Tavern Brawl patch}}
 
If you have a [[Gladiator's Longbow]] equipped, play [[Blade Flurry]], click [[Hero Power]] to equip a new weapon, then queue an attack before the Gladiator's Longbow visually disappears, your hero is visually [[Immune]] but not actually Immune. The fake Immune will go away if you make another attack with a second Gladiator's Longbow (or possibly under other circumstances).

[[Kezan Mystic]] maintains the play order of the stolen [[Secret]], but always places it at the end, where a newly played newest Secret would appear. This is likely a visual bug, as under all other circumstances, play order and visual order are the same thing.

In Tavern Brawl [[Battle of Tol Barad]], if you play Succubus and it discards the spell created by the Tavern Brawl rule, the same glitch occurs.

====Mana tray====
 
{{lv|Patch 3.0.0.9786|TGT patch}}
 
If you pick up a card in the hand to play it (e.g. [[Dragon's Breath]]) right before it visually gets discounted by on-going animation effects (such as Deaths), it will visually highlight the old amount of [[Mana|Mana crystal]]s in the bottom right corner.

* http://imgur.com/vS6aXQx
 
 
You can desync your available Mana Crystal display in the Mana Tray by playing another card quickly after using [[Innervate]].
 
* https://www.youtube.com/watch?v=RoOlKi6uogs
 
 
You can also do it with [[Wild Growth]].
 
* http://imgur.com/w26XDxj
 
 
You can also do it with [[Grove Tender]].
 
* https://www.youtube.com/watch?v=u3L50eGC0ug&t=0m32s
 
 
If you perform actions at the exact same time as your opponent concedes and the game tells you 'Too late! Your turn is over.' you will sometimes gain mana rapidly until it say 20/10 mana.
 
* https://www.reddit.com/r/hearthstone/comments/3qri0j/i_glitched_and_somehow_had_20_mana/
 
 
====Mana tray (Overload)====
 
{{lv|Patch 3.0.0.9786|TGT patch}}
 
If you play any [[Overload]] card and then [[Felguard]] (in this order), the last mana crystal will not have the lock icon displayed on your next turn.
 
* https://www.reddit.com/r/hearthstone/comments/3f9rp7/if_you_play_fel_guard/
 
* https://www.youtube.com/watch?v=H40pak0YKrg
 
 
You have 10 mana and use a card with 2 overload. On your next turn you play reduced [[Nourish]] for 0 mana (due to the effect of [[Emperor Thaurissan]]), spend another 8 mana and then play [[Lava Shock]] for 2 mana. The mana tray will display 2/10 available crystals, but there will be more crystals highlighted incorrectly.
 
* http://imgur.com/qT2MxlX
 
 
You have 10 mana and use an overload card for less mana than the card's overload ([[Forked Lightning]], [[Dust Devil]] or cards discounted by Emperor Thaurissan). On your next turn some of your available mana crystals will not be highlighted. How many crystals will not be highlighted will depend on each card's final cost subtracted from the card's overload value. So for example playing Forked Lightning will cause one of your crystals to not be highlighted properly.
 
* http://imgur.com/VBj3H6m (Played Forked Lightning)
 
* http://imgur.com/51rKB5w,1BcpUna (Played 5 cards for 0 mana total with a total amount of 5 overload)
 
 
You have 5 mana and use two of the following cards: Forked Lightning or Dust Devil to get 4 mana overload. On your next turn you will play 1 mana card with 1 overload, such as [[Lightning Bolt]]. The overload lock will not be displayed on the last mana crystal on your following turn.

====Mimiron's Head====
 
{{lv|Patch 4.0.0.10833|LoE patch}}
 
Due to how [[Mimiron's Head]] visual effects work, its animation and board images of [[Mech]]s can glitch out. In particular, if a different effect (such as [[Nightmare]], [[Homing Chicken]] or [[Doomsayer]] marks minions TO_BE_DESTROYED before Mimiron's Head does (See http://hearthstone.gamepedia.com/Advanced_rulebook#.27Pending_destroy.27_bugs_and_effects and Rule 5), they will visually destroy (instead of remaining visibly on the board) when the Forced Death Phase of Mimiron's Head runs, becoming unable to be used in the animation. Failure to complete the animation will leave uninteractive visual 'copies' behind on the board.
 
 
Four scenarios with visual side-effects are shown below:
 
 
One mech visually dead (V-07-TR-0N spawned, 1 mech in animation with Mimiron's Head)
 
* https://www.youtube.com/watch?v=buvwFmFjvmQ
 
 
All mechs visually dead except Mimiron's Head (V-07-TR-0N spawned, no animation)
 
* https://www.youtube.com/watch?v=WYQlirNW6aQ
 
 
All mechs visually dead (V-07-TR-0N spawned, no animation)
 
* https://www.youtube.com/watch?v=1wjoFIU74rE
 
 
If you play Doomsayer, [[Alarm-o-Bot]], Mech, Mimiron's Head in this order, with another mech in hand (V-07-TR-0N spawned, no animation)
 
* https://www.youtube.com/watch?v=mujKLgrEgpM
 
 
====Misdirection====
 
{{lv|Patch 2.8.0.9554|TGT pre-purchase patch}}
 
If you attack into an enemy hero who played [[Misdirection]], then play new minions quickly before the animation resolves, the crosshair can fly over the new minions, even though they are not eligible to be misdirected into.
 
*https://www.youtube.com/watch?v=ways3ibUQas
 
 
====Multiple animations going off very quickly====
 
{{lv|Patch 2.7.0.9166|Tavern Brawl patch}}
 
If you manage to steal [[Deathcharger]] from one of the [[Curse of Naxxramas|Naxxramas]]' bosses and kill it with [[Baron Rivendare]] on board, its Deathrattle animation triggers twice so quickly that it only appears to trigger once.
 
* http://www.reddit.com/r/hearthstone/comments/2csozi/bug_baron_rivendare_does_not_activate/
 
* https://www.youtube.com/watch?v=19uq0FsmWlk
 
 
The same can be observed with two [[Living Bomb (Tavern Brawl)|Living Bombs]] exploding simultaneously at the start of the turn.
 
* https://www.youtube.com/watch?v=zYNWKSr-jqM
 
 
====Nozdormu (multiple copies)====
 
{{lv|Patch 2.7.0.9166|Tavern Brawl patch}}
 
If you manage to get multiple copies of [[Nozdormu]] in play, his sandstorm animation will stack. With sufficient Nozdormus in play, the sandstorm grows thick enough that it will eventually obscure the Battlefield from the player's view, making the game extremely difficult to play.
 
* https://www.youtube.com/watch?v=_Z2ZU-cIoG8
 
 
====Nozdormu and return to hand effects====
 
{{lv|Patch 4.0.0.10833|LoE patch}}
 
Returning [[Nozdormu]] to hand by effects like [[Freezing Trap]] or [[Sap]] will cause the sandstorm effect to remain for the remainder of the match. This is purely a visual bug, turns no longer last 15 seconds (See [[#Nozdormu|Nozdormu timer bug]]).
 
 
====Nozdormu and Deathlord====
 
{{lv|Patch 2.5.0.8416}}
 
If a [[Nozdormu]] is brought into play via the death of [[Deathlord]], the sandstorm effect is not activated. This is purely a visual bug, turns will still last 15 seconds (See [[#Nozdormu|Nozdormu timer bug]]).

====Obtained Secrets====
 
{{lv|Patch 3.2.0.10604|2015-10-20}}
 
If your opponent plays a [[Secret]] obtained from [[Nefarian]] or similar cards like [[Burgle]] or [[Spellslinger]], the text "Created by ..." will be missing on the card when it enters the play.
 
* http://imgur.com/UMyPtCC
 
 
====Played minion visually returns to hand====
 
{{lv|Patch 4.0.0.10833|LoE patch}}
 
If you play a minion that has a [[Choose One]] or a minion that has a Battlecry that targets another Character, then right-click to cancel playing the minion, followed quickly by playing another minion from your hand (while the first minion is still animating back from the Battlefield back into your hand), the second minion will get played into the Battlefield, but sometimes will also visually bounce back to your hand right after it has been played. The minion is considered played and in the Battlefield with mana costs paid for, but will visually remain in your hand until you play another card, whereupon the minion will go back from your hand into the correct Battlefield position.

====Poisonous minions====
 
{{lv|Patch 3.2.0.10604|2015-10-20}}
 
If minion with the [[Poison]] ability such as [[Emperor Cobra]] is reduced to 0 attack by [[Shrinkmeister]], when attacking with it or into it, a Skull symbol incorrectly shows that the target will be killed by Poison. If the target has [[Divine Shield]] or is [[Immune]], causing the Poisonous minion to do 0 damage and thus not trigger, the Skull symbol is also incorrectly shown.

====Return to hand effects and minions with modified cost====
 
{{lv|Patch 4.0.0.10833|LoE patch}}
 
Returning to hand and replaying minions that have their mana cost actively reduced or increased (by [[Mana Wraith]] or similar effects) will display their original cost (only for the opponent) on the card when it enters the play.
 
* https://www.youtube.com/watch?v=J8mM0S4OT88
 
 
The same bug can be observed by returning and replaying a [[Mountain Giant]]/[[Molten Giant]]/[[Sea Giant]]/[[Clockwork Giant]]. It will display its original cost on the card (only for the opponent) when it enters the play.
 
* https://www.youtube.com/watch?v=jRB4Rla805s
 
 
This can also be observed by replaying a minion that has been affected by [[Freezing Trap]].
 
* http://imgur.com/ZOsyViG
 
 
====Return to hand effects on stolen minions====
 
{{lv|Patch 3.0.0.9786|TGT patch}}
 
If you steal a minion that has been on the board for multiple turns with [[Cabal Shadow Priest]] or [[Shadow Madness]], return the stolen minion to your hand and replay it again, it will not have the "Zzz" summoning sickness animation indicating that it cannot attack.
 
* http://imgur.com/qgfvff6 (Frostwolf Grunt)
 
 
====Return to hand effects on transformed minions====
 
{{lv|Patch 2.7.0.9166|Tavern Brawl patch}}
 
If you return a [[Sheep]] back into your hand and replay it, it will not show the "Zzz" summoning sickness animation. It does not matter if the Sheep attacked that turn or not. For this bug to happen, the Sheep needs to be transformed (by [[Polymorph]]) on prior turns. If you [[Polymorph]] a minion this turn, return the Sheep back to your hand and replay it all in one turn, it will show the summoning sickness animation correctly. The same behavior can be observed with [[Hex]].

====Savage Combatant====

====Secrets with modified cost====
 
{{lv|Patch 4.0.0.10833|LoE patch}}
 
When your opponent plays a [[Secret]] that has its mana cost modified, it will display the mana cost in white color on the card when it enters the play.
 
* http://imgur.com/mgxR3bR
 
 
====Shadowstep====
 
{{lv|Patch 2.7.0.9166|Tavern Brawl patch}}
 
If you play a minion and [[Shadowstep]] it quickly multiple times before it goes visually into the hand, the minion's final image on the board may appear smaller.
 
* http://imgur.com/ivzJWfa
 
 
====Spells with modified cost (aura)====
 
{{lv|Patch 4.0.0.10833|LoE patch}}
 
When your opponent plays a [[Spell]] that had its mana cost modified by an aura, such as effects of [[Loatheb]] or [[Sorcerer's Apprentice]], it will display the original mana cost on the card when it enters the play. Spells that had their mana cost modified by a buff, such as effects of [[Emperor Thaurissan]] or [[Nefarian (Tavern Brawl)|Nefarian]]'s hero power update the mana cost properly. If the Spell has been affected by both an aura and a buff, only the buff modification will be shown.

====Temporary gap in hand====
 
{{lv|Patch 4.0.0.10833|LoE patch}}
 
If you quickly play a spell after you played another card, a gap will form in your hand for a brief moment. If there are any minions that trigger while you cast your spell, e.g. [[Lorewalker Cho]], the gap stays there for a longer period of time.
 
* http://imgur.com/5yIJVXm (Casting multiple spells while Lorewalker Cho is on the board)
 
* http://imgur.com/0cT3in0 (Antique Healbot + Eviscerate)
 
* http://imgur.com/bXIvCjr (Angry Chicken + Rusty Horn)
 
 
If you draw an extremely large number of cards, and continue to queue up more played cards from your hand while doing this, the gap in your hand increases with no upper limit. This could cause a card to be all the way off-screen and be impossible to select until animations finished.

====Tilted minions====
 
{{lv|Patch 3.2.0.10604|2015-10-20}}
 
Sometimes, your opponent's minion will appear on the board at an angle. Your opponent does not see this bug.

====Transform effects====
 
{{lv|Patch 3.2.0.10604|2015-10-20}}
 
If you play [[Faceless Manipulator]] while an animation of a previously played [[Battlecry]] is ongoing, sometimes the post-transform minion will slice into place from the left side of the battlefield.

====Weapon not covered====
 
{{lv|Patch 3.1.0.10357|Mech War Tavern Brawl patch}}
 
Sometimes, your (or your opponent's) weapon does not get covered after ending the turn. This might have to do something with equipping the weapon and clicking the end turn quickly before the animations are resolved.

====Windfury and Transform effects====

If you [[Transform]] a minion that has [[Windfury]], its Windfury visual effect remains on the battlefield until the game ends or you reconnect.

* https://www.youtube.com/watch?v=R1HTkLmvbM4
 
 
Dying (due to [[Life Tap]]) or conceding during [[Nexus-Champion Sareed]]'s animation has a similar effect:
 
* https://www.youtube.com/watch?v=vZZRkQpbiSQ
 
 
===Network bugs===
 
 
====Connection loss====
 
A very common bug - if the connection between your client and the server is lost, sometimes you will never receive notification that anything happened. Symptoms are that the rope never burns, emotes still work but you never see your opponent's highlight change or cards get played. If the connection is later re-established, the server will send all of your opponent's actions, over however many turns you missed, all at once. If you think you have disconnected, close and re-open the client to try and reconnect to your game before your next turn is over!
 
 
* https://www.youtube.com/watch?v=YiORBZ4lTgA&t=8m40s (an extreme example - if you remain disconnected for too long, there is an invisible card in your hand and your mana for the next turn is not correctly displayed)
 
 
It is believed that the 'infinitely long turn' effect can be caused by dropping only one packet (see the packet loss section below) - so even if your connection is solid, it may still rarely happen.
 
 
====Server/client desync (packet loss)====
 
Very rarely, your opponent will take an action, but the server will fail to send the action to your Hearthstone client. The state of the game is still correctly including all actions on the server, and the server will still correctly tell you the new Health of characters whenever damage takes place, but from your end, minions will mysteriously take the wrong amounts of damage, or die when taking non-fatal damage, or other consequences caused by you having missed a minion or spell being played.
 
 
* http://us.battle.net/hearthstone/en/forum/topic/17345257882 (contains video)
 
* http://us.battle.net/hearthstone/en/forum/topic/17605023209 (the likely desync is that the enemy's Shielded Minibot attacked the totem on a previous turn but the packet containing that action was dropped, but it is unconfirmed)
 
* https://www.youtube.com/watch?v=Sii5lHvQP84&t=5m49s (The desync is that the enemy Rogue hit the Sorcerer's Apprentice once with the dagger before using Blade Flurry - later the Rogue's HP was correctly updated following damage taken)
 
* https://www.youtube.com/watch?v=YiORBZ4lTgA&t=5m30s (A Druid of the Claw was played in 4/6 Taunt mode, but Kripp's client wasn't told about it, so he couldn't attack past it)
 
* http://us.battle.net/hearthstone/en/forum/topic/17906601421 (A Raging Worgen took one extra damage, but the packet containing that information was dropped)
 
* https://www.youtube.com/watch?v=raLgJ-I488s&t=2m10s (The client was told that the minion died, but NOT told that the minion was moved to the graveyard, so the client moved it back. However, since the server knows it's dead, it never sent actions that involved it, and thus no green highlight.)
 
 
===Gameplay bugs===
 
 
====After Play Phase====
 
{{lv|Patch 4.0.0.10833|LoE patch}}
 
Normally after each outermost Phase, we run the following Steps:
 
 
* Aura Update (Health/Attack)
 
* Summon Resolution Step
 
* Aura Update (Health/Attack)
 
* Death Creation Step
 
* Aura Update (Other)
 
 
However, when you play a minion, after the After Play Phase and before the After Summon Phase, only the following steps run:
 
 
* Aura Update (Health/Attack)
 
* Aura Update (Other)
 
 
This is the only Phase in Hearthstone documented to be missing Steps after it. Besides the missing Steps, they are in all other ways two distinct Phases.
 
 
Example consequences of this bug:
 
* If you have a Knife Juggler, play a minion and it dies to Snipe, your friendly Knife Juggler will still trigger.
 
* If you have a Rumbling Elemental and a Knife Juggler (any order of play), play a minion and the Rumbling Elemental mortally wounds an opponent Explosive Sheep, the Explosive Sheep will not die until after the Knife Juggler also triggers.

* https://www.youtube.com/watch?v=djSKr0dO4ds
 
 
====Area of effect damage effects====
 
{{lv|Patch 4.0.0.10833|LoE patch}}
 
[[Explosive Sheep]] ignores (does not continue to damage) mortally wounded (0 or less Health) minions. However, all other AoE damage that has been tested overkills mortally wounded characters, and [[Healing Totem]] can heal mortally wounded minions.
 
 
* https://www.youtube.com/watch?v=IUMQ7MAilJ0
 
 
====Bane of Doom, Mortal Coil on already dead minion====
 
{{lv|Patch 3.0.0.9786|TGT patch}}
 
[[Bane of Doom]] and [[Mortal Coil]] targeting a minion that dies before the spell goes off may or may not trigger the side-effect, seemingly inconsistently.
 
* https://www.youtube.com/watch?v=MYGSoWbaIAM
 
 
Technical explanation:
 
 
In Hearthstone, Spells and Battlecries targeting a minion still activate and affect that minion if the minion is killed in an earlier Phase, such as by [[Violet Teacher]] spawning a token and a friendly [[Knife Juggler]] reducing it to 0 Health. Furthermore, when the minion moves to the graveyard, its attributes, such as Health, are reset.
 
 
If [[Bane of Doom]] or [[Mortal Coil]] are used to target such a minion, they damage the minion after it has been moved to the graveyard. This means their side-effect will go off if they reduce the reset version of the minion to 0 or less Health, regardless of their state prior to dying.
 
 
====Boneguard Lieutenant====
 
{{lv|Patch 3.0.0.9786|TGT patch}}
 
There are two reports of people picking up [[Boneguard Lieutenant]] after using their [[Hero Power]] and not getting the [[Inspire]] effect.

====Brawl====
 
{{lv|Patch 3.1.0.10357|Mech War Tavern Brawl patch}}
 
Casting [[Brawl]] that causes a [[Violet Teacher]]/[[Illidan Stormrage]] to spawn a minion, that causes a [[Knife Juggler]] to throw a knife, that causes the death of [[Abomination]]/[[Explosive Sheep]]s that clears the entire board of minions, will result in a situation where Brawl resolves with 0 minions on the board. When this happens, the Brawl animation runs forever, requiring a client restart.
 
* https://www.youtube.com/watch?v=5ItppVLJqko&t=38
 
 
====Charge====
 
{{lv|Patch 4.0.0.10833|LoE patch}}
 
Sometimes you cannot attack with a played [[Charge]] minion. Instead of being able to click on and order the Charge minion to attack, you will get 'dust clouds' from clicking on the ground beneath it, even if the minion survives a turn. This is a client side bug only - the minion is really in play, and disconnecting and reconnecting should make it interactible again. It is theorized that if you do not click on the charge minion while it's being put into play, the bug will not occur.

====Coldarra Drake/Garrison Commander and Steal effects====
 
{{lv|Patch 3.0.0.9786|TGT patch}}
 
[[Steal]]ing a [[Coldarra Drake]]/[[Garrison Commander]] does not refresh your [[Hero Power]] if you already used it that turn. When a Coldarra Drake/Garrison Commander is played, summoned or transformed into, in the next Aura Update (Health/Attack) Step, it will refresh your Hero Power. In addition, during the Inspire Phase, Coldarra Drake/Garrison Commander queue and trigger to refresh your Hero Power.

As a consequence of the above rules, stealing (using [[Mind Control]] or otherwise) a Coldarra Drake/Garrison Commander does not refresh your Hero Power:

====Combat canceled after death processing====
 
{{lv|Patch 3.2.0.10604|2015-10-20}}
 
If you begin combat, but triggers on preparing to attack (during the "Combat Preparation Phase") remove your target first, the attack aborts and you are not exhausted or lose durability. This is the normal case, and can be seen here: https://www.youtube.com/watch?v=X1MkS7_jj0U
 
 
However, if the target is alive after the "Combat Preparation Phase" BUT the Death Phase following the "Combat Preparation Phase" THEN causes your target to die, a glitch occurs where the attacker is stuck in mid air and cannot be used to attack again. For example, an enemy minion is summoned, triggering an enemy [[Knife Juggler]], mortally wounding an allied [[Boom Bot]]. During the subsequent Death Phase the Boom Bot Deathrattle mortally wounds the defender, and THEN it is removed from play, and then combat glitches out. This has happened with both Hero and Minion attackers. The extra Death Phase seems to be the culprit.

====Commanding Shout====
 
{{lv|Patch 3.0.0.9786|TGT patch}}
 
 
[[Commanding Shout]] states that your minions can't be reduced below 1 [[Health]] this turn. However, Commanding Shout only applies to minions after the [[Advanced_rulebook#Summon_Resolution_Step|Summon Resolution Step]]. Therefore, there are multiple scenarios in which your new minions won't receive the buff, for example:
 
 
If you steal a minion, it does not gain the Commanding Shout enchantment.
 
* https://www.youtube.com/watch?v=QC8_jNOvdEs&t=11m33s
 
 
If one of your minions is [[Transform]]ed with a spell transformer, the post-transformed minion does not have the enchantment.
 
* https://www.youtube.com/watch?v=QC8_jNOvdEs&12m49s
 
 
If you play [[Grim Patron]], Commanding Shout and [[Bouncing Blade]], it should result in a board full of 3/1 Patrons for the player. However, this is not the case.

* https://www.youtube.com/watch?v=QC8_jNOvdEs&13m10s
 
* https://www.youtube.com/watch?v=iMb5Vs49oIE
 
 
Below are the examples where Commanding Shout works correctly:
 
 
If one of your minions gets stolen by [[Sylvanas Windrunner]]' Deathrattle, it will keep the enchantment until the end of your turn.
 
* https://www.youtube.com/watch?v=QC8_jNOvdEs&12m1s
 
 
If one of your minions is Transformed with a minion transformer, the post-transformed minion will receive the enchantment.
 
* https://www.youtube.com/watch?v=QC8_jNOvdEs&12m22s
 
 
If you play a self-transformer like a [[Druid of the Claw]], the final minion will also receive the enchantment.

====Commanding Shout and Sea Reaver====
 
{{lv|Patch 3.1.0.10357|Mech War Tavern Brawl patch}}
 
If you play [[Commanding Shout]] with a 1 health allied minion in play, and the drawn card is [[Sea Reaver]], the 1 health allied minion will be reduced to 0 health, even though Commanding Shout's card text says it draws a card last of all.

====Dancing minions====
 
{{lv|Patch 2.7.0.9166|Tavern Brawl patch}}
 
In [[Showdown at Blackrock Mountain]], when playing as [[Ragnaros_the_Firelord_(Tavern_Brawl)|Ragnaros]], if you have [[Core Hound Pup]]s out on the board, your minions may swap position after you play them. The cause seems to be playing minions fast before or after casting [[Core Hound Puppies]], making the played minion be between the Core Hound Pups on the server but not on the client.
 
* https://www.youtube.com/watch?v=k-Np0kSJeco
 
 
It appears to also occur with [[Feral Spirit]].

====Deathlord====
 
{{lv|Patch 3.2.0.10604|2015-10-20}}
 
If a sequence of events causes a [[Deathlord]] to die, and its Deathrattle brings into play a low health minion (let's call this Minion X) that dies immediately to another Deathrattle (usually [[Explosive Sheep]], [[Abomination]] or [[Unstable Ghoul]]), Minion X's card image will stay bugged on the board in its death position and physically prevent any interaction with any future minion that occupies that same board position. This is because the minion under Minion X's card image cannot be targeted by the mouse cursor. All the threads below contain screenshots of this bug.

===="Draw a card" spell====
 
{{lv|Patch 3.0.0.9786|TGT patch}}
 
When you use [[Wrath]] (1 damage version) on your own [[Mech-Bear-Cat]], you first draw the card from your deck, then the [[Spare Part]]. When you do the same with [[Starfire]], you first draw the Spare Part, then the card from your deck.
 
[[Damage]] first then, Card Draw (Spare Part first):

====Echoing Ooze and Frozen effects====
 
{{lv|Patch 3.1.0.10357|Mech War Tavern Brawl patch}}
 
There is a bug where a [[Frozen]] [[Echoing Ooze]] will not copy the Frozen debuff.

====Echoing Ooze and Power Overwhelming====
 
{{lv|Patch 2.7.0.9166|Tavern Brawl patch}}
 
If you use [[Power Overwhelming]] on your Echoing Ooze, at the end of your turn, the Ooze clones itself. Then the original Ooze dies horribly, and the clone survives. This 5/6 clone then dies horribly at the end of your opponent's turn. This directly contradicts what Ben Brode said should happen, but is consistent with how triggers are queued in other cases (in particular, if a trigger appears after the queue is finished, it is not added to the queue).

====Elemental Destruction====
 
{{lv|Patch 3.0.0.9786|TGT patch}}
 
[[Elemental Destruction]] deals its damage one by one and runs on-damage triggers in between, rather than all at once then run all on-damage triggers. Lightning Storm has the same behaviour.
 
* https://www.youtube.com/watch?v=phurzsurH2k&t=9m55s
 
 
====Enrage====
 
{{lv|Patch 4.0.0.10833|LoE patch}}
 
Previously, Enrage Enchantments would be processed in play order - for example if you Aldor/Enrage a minion it has 1+(enrage effect) attack, but if you Enrage/Aldor a minion, it has 1 attack. In addition, un-Enraging and re-Enraging a minion would create a new Enrage Enchantment with new play order.
 
* https://www.youtube.com/watch?v=StimopyMMsA
 
 
However, as of Patch 4.0.0.10833 (LoE patch), the Enrage Enchantment always has priority earlier than all other Enchantments. For example, if a minion is Aldored then Enraged, it has 1 Attack still, and if a minion is Reversing Switched then Enraged, the Enrage does not change the minion's Attack. It is not clear if this is a bug or an undocumented change to the Enrage mechanic.

====Faceless Manipulator====
 
{{lv|Patch 4.0.0.10833|LoE patch}}
 
When you target a buffed minion with [[Faceless Manipulator]], not all of the buffs copy. (However, all of the [[Damage]] copies, meaning the Faceless Manipulator might have 0 or less [[Health]] and die.)

* https://www.reddit.com/r/hearthstone/comments/3si0f0/is_this_a_bug/
 
 
The pattern seems to be that a self-applied buff is copied as though it was only applied once, not the actual number of times it applied. It seems to happen with [[Mirror Entity]] as well.
 
 
* http://us.battle.net/hearthstone/en/forum/topic/19877517587
 
 
====Faceless Manipulator and Cobalt Guardian/Murloc Tidecaller====
 
{{lv|Patch 2.7.0.9166|Tavern Brawl patch}}
 
Using [[Faceless Manipulator]] to transform into a friendly [[Cobalt Guardian]] causes the friendly Cobalt Guardian to trigger, the Faceless Manipulator to do the battlecry flash and gain a divine shield, then a friendly [[Knife Juggler]] to trigger. This is a Bug because Cobalt Guardian triggers before the Battlecry that should have made it a Mech even happens, allowing the divine shield to be copied. [[Murloc Tidehunter]] vs [[Faceless Manipulator]] has the same bug, where the transformation and trigger occur before the Battlecry, allowing the extra buff to be copied. This causes a visual bug as well.
 
 
[[One-eyed Cheat]], [[Starving Buzzard]] and [[Undertaker]] all do not have this bug and the self-transformation of Faceless Manipulator and other minions are performed at the expected time. Later, during the "summoning catchup step" (see the [[Advanced rulebook]] for more information), the minion notices the minion now satisfies its condition and triggers, but this is the intended and correct ordering.

====Fel Reaver and Overload====
 
{{lv|Patch 4.0.0.10833|LoE patch}}
 
If your opponent has a Fel Reaver in play and you play an Overload card, you don't gain any Overload. So cards like Tunnel Trogg will not gain any Attack.

====Flame Leviathan====
 
{{lv|Patch 4.0.0.10833|LoE patch}}
 
If an [[Unstable Portal]] generates a [[Flame Leviathan]], the opponent can see this in the history sidebar on mouseover and know that a Flame Leviathan is obtained. The 2 damage AoE effect does not occur since the card was not drawn normally from the deck.

====Foe Reaper====
 
{{lv|Patch 2.7.0.9166|Tavern Brawl patch}}
 
[[Foe Reaper 4000]] does the initial damage, allows on-damage triggers to run, then deals damage to the minion to the right, then to the left. For example, a new Imp is spawned by Imp Gang Boss causing the For Reaper to hit that instead of the original adjacent minion.
 
http://us.battle.net/hearthstone/en/forum/topic/17346967051
 
 
Same bug was previously observed with [[Swipe]] and [[Explosive Shot]], but they have been fixed in [[Patch 2.7.0.9166]], while Foe Reaper 4000 still remains unchanged.
 
 
====Garrison Commander and Snipe====
 
{{lv|Patch 3.0.0.9786|TGT patch}}
 
If you use your [[Hero Power]], play [[Garrison Commander]], you will see your Hero Power refresh, [[Snipe]] trigger and the Garrison Commander die. However, your Hero Power remains available to use still. In general, your Garrison Commander or [[Coldarra Drake]] dying does not exhaust your Hero Power, which might seem unintuitive if you expect it to work like [[Windfury]] or like other [[Aura]]s like [[Prophet Velen]], which turn off when they leave play.

====Gladiator's Longbow and Explosive Trap====
 
{{lv|Patch 4.0.0.10833|LoE patch}}
 
You will take damage if you attack with a [[Gladiator's Longbow]] into an [[Explosive Trap]]. Ben Brode, [https://twitter.com/bdbrode/status/480033773673668608 tweeted] on 21 June 2014 that this is likely a bug:
 
 
* Q: Gladiator's Longbow. Even though the immune shimmer appears over the hero, they are still damaged by Explosive Trap.
 
* A: it's a bug. We're looking into it.
 
* Q: What one is the bug? That we're damaged by Explosive Trap or that the immune shimmer appears?
 
* A: probably the fact that you're damaged
 
* Q: Been [http://www.hearthpwn.com/forums/hearthstone-general/general-discussion/12576-big-flaw-with-a-hunter-card-blizz-pls-fix debating on Hearthpwn]. Some folks figure damage shouldn't occur. Some think it should and shimmer is the bug. Clears it up.
 
* A: I think the text makes you feel like you shouldn't take damage even if there were no effect.
 
 
This is in contrast with attacking into a [[Paladin]] with an [[Eye for an Eye]] secret, where the [[Hunter]] will not take any damage from the secret. Image Proof: http://imgur.com/wZvCYy8,VFM8sUf (2 images). If a Hunter attacks a [[Water Elemental]] with the bow, it will take no damage from the Water Elemental as expected. Since the Water Elemental did not do any damage, it will also not Freeze the Hunter. Image Proof: http://imgur.com/flp9pWM,165e0KS (2 images).

====Gorehowl, Misdirection, Explosive Trap====
 
{{lv|Patch 2.7.0.9166|Tavern Brawl patch}}
 
If you attack with [[Gorehowl]] into an opponent's hero, get redirected by [[Misdirection]] into one of his minions that dies to [[Explosive Trap]], your attack gets cancelled and you can attack that turn again. If you attack again into opponent's hero or his minions, Gorehowl's attack or durability will not reduce. This is a bug. If you attack again next turn, the attack or durability will reduce properly.

====Gormok the Impaler====
 
{{lv|Patch 2.7.0.9166|Tavern Brawl patch}}
 
[[Gormok the Impaler]] only checks the condition of his targeted [[Battlecry]] 'If you have at least 4 other minions' when played and targeted. If you fail the condition during the Battlecry Phase, then the Battlecry still has its full effect.
 
* https://www.youtube.com/watch?v=afqdiQbt-cQ
 
 
However, [[Blackwing Corruptor]] and [[Rend Blackhand]], the two targeted 'If you're holding a [[Dragon]]' minions, require the condition when played and targeted, and also check it a second time when the Battlecry Phase begins - if it is now failed, the Battlecry visually animates but does not have its effect.
 
* https://www.youtube.com/watch?v=wCKhbmHNLAs&t=6m38s
 
 
Since these two are inconsistent, one or the other is a bug.
 
 
====Holy Wrath and Spell Damage====
 
{{lv|Patch 3.1.0.10357|Mech War Tavern Brawl patch}}
 
When casting [[Holy Wrath]] and the drawn card has a casting cost of 0 (such as the [[Wisp]] or [[Target Dummy]]), the damage done by the spell remains at 0 even if the player has [[Spell Damage]]. Using Holy Wrath on a minion with Divine Shield in this situation will not break Divine Shield.
 
 
This bug is similar to 2 bugs that has already been fixed, namely using [[Shield Slam]] with 0 Armor and using [[Shadowflame]] on a 0-attack minion while having Spell Damage used to deal 0 damage incorrectly.

====Immune (effect) and random effects====
 
{{lv|Patch 3.2.0.10604|2015-10-20}}
 
Random effects can target an [[Immune]] character. For example, [[Avenging Wrath]], [[Ragnaros the Firelord]] or [[Ogre Brute]] can still target an Immune character randomly, but will deal 0 damage. This is cited to be unintended specifically for Avenging Wrath.

====King's Elekk====
 
{{lv|Patch 4.0.0.10833|LoE patch}}
 
[[King's Elekk]] doesn't trigger draw-based effects, such as [[Chromaggus]]. With Chromaggus on the field, King's Elekk is played and the [[Joust]] is won. The card is drawn, but no copy was put in the hand.

====Knife Juggler====
 
{{lv|Patch 4.0.0.10833|LoE patch}}
 
When you have a [[Knife Juggler]] on the field and play a [[Choose One]] minion that does not transform itself (such as [[Keeper of the Grove]]), Knife Juggler will not trigger.

Sword of Justice also will not trigger, because Sword of Justice is also a trigger in the After Summon Phase.

====Lightbomb====
 
{{lv|Patch 3.2.0.10604|2015-10-20}}
 
When casting [[Lightbomb]] and there is a [[Frothing Berserker]] on the board, the Frothing Berserker will activate as other minions are damaged by Lightbomb and may grow large enough in Attack to subsequently get killed by Lightbomb. This is unintended as all damage should be dealt before any damage triggers are activated.

However, in the middle of a [[Lightbomb]] cast, auras do not turn off. For example, a [[Dire Wolf Alpha]] being reduced to 0 HP will not allow a [[Mechwarper]] next to it to survive - it still takes 3 damage and dies.

====Mad Scientist====
 
{{lv|Patch 3.0.0.9786|TGT patch}}
 
 
Normally, there is a limit of 5 secrets that a player may have in play. However, Mad Scientist's Deathrattle ignores this limit. Mad Scientist will correctly not put into play a second copy of currently active secrets, but will put additional different secrets into play if available in the player's deck. This has been shown to allow at least 11 different secrets to be active on a hero at the same time. Secrets beyond the 5 limit will activate and take effect normally, and in the correct order.

The potential for Mad Scientist's secret (such as [[Mirror Entity]]) to trigger immediately off the playing of a minion whose [[Battlecry]] kills the Scientist (such as [[Fire Elemental]]) is listed as a [http://us.battle.net/hearthstone/en/forum/topic/9677847863 Known Issue] on the official Bug Reports forum as of January 2015, and was initially being "looked into" by developers. However, subsequent tweets by Ben Brode have treated the behavior as intended, albeit unintuitive. It is unknown whether the behavior will be changed.

====Malorne and Baron Rivendare====
 
{{lv|Patch 2.7.0.9166|Tavern Brawl Patch}}
 
 
Community Manager Whirthun tweeted that if a [[Malorne]] dies with [[Baron Rivendare]] in play, only 1 copy of Malorne gets shuffled into the deck (twice). However, actual playtesting reveals that 2 copies of Malorne actually gets shuffled into the deck. It is unclear whether this is a bug at the moment. Community Manager Zeriyah has replied in the same thread that this is being looked into. * https://twitter.com/CM_Whirthun/status/539919240933806080

====Mirror Entity====
 
{{lv|Patch 2.7.0.9166|Tavern Brawl patch}}
 
[[Mirror Entity]] copies a minion even if it is at 0 or less Health (e.g. due to [[Snipe]] triggering first). The copy has the same Health and thus dies as soon as the After Play Phase ends. This is in contrast to, for example, [[Freezing Trap]], which correctly remains hidden if the minion is already mortally wounded.

* http://www.reddit.com/r/hearthstone/comments/384q3p/til_snipe_mirror_entity_copy_minion_with_dmg/
 
 
[[Mirror Entity]] creates a fresh, undamaged copy of a minion if the played minion was already dead and removed from play in an earlier Phase. This is in contrast to, for example, [[Snipe]], which won't trigger in the same circumstance.

====Nefarian====
 
{{lv|Patch 2.6.0.8834}}
 
If [[Nefarian]] is played against a player that had his hero replaced with [[Ragnaros (hero)|Ragnaros]] via [[Majordomo Executus]], 2 spells from the original hero class should be given. Instead, 2 [[Tail Swipe]]s are currently given instead, the cards that are given when Nefarian is played against [[Adventure]] [[boss]]es.

* https://www.youtube.com/watch?v=w_Cbl41_G-8
 
 
If Nefarian is played against an Adventure Boss, 2 Tail Swipes should be given to the player. However, when played against [[Noth the Plaguebringer]], Nefarian gives the player 2 Mage spells. When played against [[Heigan the Unclean]], Nefarian gives the player 2 Warlock spells. This is the case on both Normal and Heroic difficulties.

====Nozdormu====
 
{{lv|Patch 2.7.0.9166|Tavern Brawl patch}}
 
If [[Nozdormu]] was summoned in the [[Dark Iron Arena]], the player's turn was almost always skipped instead of having 15 seconds to play because the turn timer of the player was "used up" while replaying the animations of actions made by the AI opponent.
 
* https://www.youtube.com/watch?v=msDSzkKiE3s
 
 
This bug has long existed, and is the case when played against any AI opponent, but was only really noticed during the release of the Dark Iron Arena.
 
* https://www.youtube.com/watch?v=9JoEQvGBbVs
 
 
This bug was claimed to be hotfixed later the same day Dark Iron Arena was released.
 
* https://twitter.com/PlayHearthstone/status/583781561071345664
 
* http://us.battle.net/hearthstone/en/forum/topic/13840764128#10
 
 
However, the bug persists with multiple reports daily going on the official Bug Report forums, and also affects the [[Chromaggus (boss)|Chromaggus]] encounter.
 
* https://twitter.com/bdbrode/status/595211308200370176
 
 
The bug is that the 15 seconds start counting for the player the moment the opponent player clicks the "End Turn" button, even if the attacks and animations from the opponent's turn has not completed yet. For example, if the opponent ordered 4 minions to attack and then played Nozdormu quickly and clicked End Turn, on the player's end he might only have seen 3 minions attack so far, the timer already started while he is watching the remaining attack (about 1 second), Nozdormu get played (2 seconds), and finally the "Your Turn" and card draw animation (another 2 seconds), so the player gets about 10 seconds left. The rope duration is ~20 seconds normally (including the unfurling animation), so the rope animation will play and move about twice as fast.
 
 
Since the AI plays its entire turn instantaneously, the actual amount of time the player gets out of his allotted 15 seconds is actually just 15 - (entire animation of everything the AI did on his turn) - (2 seconds to animate "Your Turn" on the screen) which is probably close to 2 seconds left.
 
 
Technically, this bug affects all game modes, but it is particularly problematic for battles against the AI.
 
 
As of [[Patch 2.7.0.9166]] (Tavern Brawl patch), this bug can be observed in Tavern Brawl, and presumably other gameplay modes tooo.

====Nozdormu vs AI====
 
{{lv|Patch 3.0.0.9786|TGT patch}}
 
If you play vs AI, [[Nozdormu]] is in play and you don't hit the end turn button in time, you are able to play your cards for the next turn before animations resolve. If you happen to play any [[Choose one]] minions, the selection would remain on the screen until the animations resolve and you get your next turn.

====Overload====
 
{{lv|Patch 4.0.0.10833|LoE patch}}
 
In 4.0, Overload was changed from occurring in the Battlecry/Spell Text Phase to occuring when you play the card from your hand. This means that if you play a spell with Overload but it is countered by Counterspell, you still gain the Overload.
 
* http://us.battle.net/hearthstone/en/forum/topic/19877077551?page=1#4
 
 
Specifically in the case of Spells, this is said to be unintended by Ben Brode.

====Poultryizer and Starving Buzzard====
 
 
{{lv|Patch 3.0.0.9786|TGT patch}}
 
When [[Poultryizer]] transforms a minion into a [[Chicken]], [[Starving Buzzard]] will trigger. Normally transformation effects that are related to a spell, such as [[Hex]] and [[Polymorph]], do not participate in the Summoning Catchup Step and thus do not trigger Starving Buzzard, [[Commanding Shout]], etc. Transformation effects that are related to a Battlecry, such as [[Faceless Manipulator]] and [[Recombobulator]], do participate in the Summoning Catchup Step and thus do trigger Starving Buzzard, Commanding Shout, etc. Poultryizer fits into the latter camp, even though it feels like it should fit into the former camp.

====Powermace====
 
{{lv|Patch 4.0.0.10833|LoE patch}}
 
If Powermace's trigger is in the same Phase as all your mechs being reduced to 0 or less Health, Powermace will not trigger on them.
 
 
* https://www.youtube.com/watch?v=IUMQ7MAilJ0&t=1m56s
 
 
This is in contradiction to how [[Avenge]], [[Anubisath Sentinel]] and [[Dark Cultist]] work - they can buff 0 or less Health minions and save them from dying as a result.

====Preparation, Summoning Stone, Gazlowe====
 
{{lv|Patch 4.0.0.10833|LoE patch}}
 
If you play Preparation, Summoning Stone, then Sprint (in that order), Summoning Stone summons a 7 drop.
 
 
If you play Summoning Stone, Prep then Sprint (in that order), Summoning Stone summons a 4 drop.
 
 
Normally the cost you play the card for determines the cost of the summoned minion (so a 4 drop should have been summoned).
 
 
* http://us.battle.net/hearthstone/en/forum/topic/19973697274
 
 
This bug also occurs with Gazlowe. If Preparation is played before Gazlowe, Gazlowe will trigger based on the cost unmodified by Preparation. If Gazlowe is played after Preparation, Gazlowe will trigger based on the cost modified by Preparation.
 
 
* https://www.youtube.com/watch?v=gNZzVj7GNpw
 
 
This is very likely to be the reason why in the Tavern Brawl [[Battle of Tol Barad]], the free spells given due to the brawl rule summon full cost minions with Summoning Stone.
 
 
* https://www.reddit.com/r/hearthstone/comments/3u88yr/this_weeks_tavern_brawl_battle_of_tol_barad/cxcpap3
 
 
Also note that the [[Battle of Tol Barad]] tavern rule applies before any other enchantments or auras, even if you got the card later. For example, if your opponent plays Loatheb, and on your turn you get a free spell, it will be reduced to 0 mana then increased by 5 mana, and thus cost 5 mana until your turn ends.
 
 
* http://us.battle.net/hearthstone/en/forum/topic/20042824204
 
 
You can exploit the previous two bugs to trick Summoning Stone into summoning an 11 or 13-19 cost minion. Instead of crashing the game, nothing happens.
 
 
* https://gist.github.com/Patashu/efc105bb844e6ccfff1a
 
 
====Preparation, Overload====
 
{{lv|Patch 4.0.0.10833|LoE patch}}
 
If you play Preparation then a spell with Overload, you do not gain the Overload.
 
 
Preparation creates an Aura attached to your Hero that destroys itself as a trigger in the On Play Phase. The moment it does, it has some unusual properties:
 
 
* It immediately updates the Mana Cost of all spells in your hand. (Normally, Auras do not update in the middle of a Phase.) This leads to a bug with Preparation and Summoning Stone/Gazlowe: https://github.com/HearthSim/hs-bugs/issues/273
 
* It makes the currently being played spell give 0 Overload.
 
 
If Preparation is played before a Tunnel Trogg, Tunnel Trogg will not see any overload and not gain any Attack. If Preparation is played after, Tunnel Trogg will gain Attack equal to overload, then Preparation will remove the overload.
 
 
Unbound Elemental triggers regardless of order of play compared to Preparation.
 
 
It is unrelated to the amount of Mana the Spell cost. For example, casting the Spell for 0 Mana using Emperor Thaurissan doesn't matter.

====Sabotage====
 
{{lv|Patch 4.0.0.10833|LoE patch}}
 
When [[Sabotage]] is used to destroy an enemy weapon and a minion, if both of them have [[Deathrattle]]s, the weapon's Deathrattle always runs and resolves first, followed by the minion's, regardless of the play order of the weapon/minion. In the more general case, the weapon is destroyed first, before the minion is destroyed - this allows the minion's abilities to still trigger from the weapon's Deathrattle.
 
* https://www.youtube.com/watch?v=5G-nBq7uAv4
 
* https://www.youtube.com/watch?v=GDF_REINyKg
 
* http://www.reddit.com/r/hearthstone/comments/32whz8/til_sabotage_destroy_weapon_first_and_then_minion/
 
 
It is currently not clear if Sabotage destroying the weapon first is intended behavior, since the general expected behavior is that both weapon and minion should be destroyed at the same time, with their deaths processed in order of age. Ben Brode had said that "Things happen one after the other, but the one thing that never happens during a card resolution or trigger is minions dying." (see Reddit thread below) but did not explicitly mention weapons dying, only minions. From the interactions of [[Death's Bite]] attacking into a [[Harvest Golem]], their Deathrattles will run in order of play, suggesting that weapon and minion deaths both follow the same general rules for death. From this, we can infer that the a sabotaged Death's Bite should not have triggered its Deathrattle before the death of the sabotaged minion.

====Sacrificial Pact====
 
{{lv|Patch 4.0.0.10833|LoE patch}}
 
When Sacrificial Pact is played, one or both players may disconnect before the Sacrificial Pact's effects have finished. If you disconnect and reconnect immediately, you may resume playing the game.

====Shadow Madness and Power Overwhelming====
 
{{lv|Patch 4.0.0.10833|LoE patch}}
 
If you use [[Shadow Madness]] to take control of an enemy minion and use [[Power Overwhelming]] to buff it, at the end of the turn, that minion will return to the enemy, survive, and retain the +4/+4 buff. At the end of your enemy's subsequent turn, it will then die. This is cited to "sound like a bug" by Ben Brode.
 
* https://twitter.com/bdbrode/status/572434608752484352
 
* https://www.youtube.com/watch?v=pIt2g9Jm9w4
 
 
If you use [[Power Overwhelming]] to buff your minion and use this minion to kill an enemy [[Sylvanas Windrunner]], if her [[Deathrattle]] takes control of this minion (assuming it survives), the minion will die immediately when you end your turn. This is probably not a bug, but proves that it is inconsistent with the [[Shadow Madness]] behavior. In the Shadow Madness/Power Overwhelming case, Power Overwhelming fails to trigger if it is not the minion controller's turn after it has returned to the enemy (with the game rule that all "end of turn" triggers occur in age order), but in the Sylvanas/Power Overwhelming case, Power Overwhelming does trigger even if it is not the minion controller's turn.
 
* http://us.battle.net/hearthstone/en/forum/topic/17084749125 (contains multiple links with discussions)
 
 
In [[Patch_2.7.0.9166]] (Tavern Brawl patch) it was tested and found that, in a given game, one player will have the minion return to the opponent's side without triggering and becoming destroyed, while the other player will have the minion return to the opponent's side then trigger and become destroyed, and that which player is which is consistent across a particular game. This may be caused by the Dominant Player Bug - perhaps all triggers for Player 1 are queued and resolved, then all triggers for Player 2 are queued and resolved. This would mean that if you do SM+PO and the minion dies for your opponent, you are player 1, because after the SM ended it stopped being a player 1 controlled minion and the second trigger

====Spellbender and Dark Wispers====
 
{{lv|Patch 3.0.0.9786|TGT patch}}
 
If a player has the [[Spellbender]] secret in play with a non-full board, and his opponent has a full board (7 minions), when his opponent plays [[Dark Wispers]] and chooses the +5/+5 to a minion option, Spellbender fails to trigger. This bug does not occur with the other [[Choose One]] Druid spells.

====Spellbender and Reincarnate====
 
{{lv|Patch 3.0.0.9786|TGT patch}}
 
When your opponent casts [[Reincarnate]] and your [[Spellbender]] intercepts, your [[Effigy]]/[[Duplicate]] will not trigger. Note that letting Spellbender proc, then casting Reincarnate on the token directly works fine.

====Steal effects (in hand)====
 
{{lv|Patch 4.0.0.10833|LoE patch}}
 
[[Steal]] effects in-hand ignore hand size limit. If you cast [[Mind Control]] on a minion, but before the [[Advanced rulebook#Playing a spell|Spell Text Phase]], the minion is returned to the opponent's hand AND your hand contains 10/10 cards, the spell will resolve by moving the minion into your hand without first checking for it being full, leading to you having 11 cards in your hand simultaneously.
 
* https://www.youtube.com/watch?v=8GbKPLvUHZk
 
 
====Steal effects (in-place)====
 
{{lv|Patch 4.0.0.10833|LoE patch}}
 
If you cast a Shadow Madness on an enemy minion while having 6 minions on the board, your first played Djinni of Zephyrs will die and all remaining Djinnis will gain charge.
 
 
https://www.youtube.com/watch?v=a0ueqgdh_NA
 
 
In addition, if you use Cabal Shadow Priest with Brann Bronzebeard in play, and stealing the enemy minion makes your board full, the second Cabal Battlecry will destroy the stolen minion, because it sees that the destination is full and counts itself.
 
 
This is likely a bug, because a similar interaction occurred if you bounced a minion from your hand to your hand while your hand was full (such as by destroying your Anub'arak with a 9/10 card hand and Baron Rivendare in play), and this interaction was changed to not discard the double bounced minion from your hand.
 
 
====Steamwheedle Sniper====
 
{{lv|Patch 3.0.0.9786|TGT patch}}
 
Contrary to the card text of [[Steamwheedle Sniper]], you can target your own [[Hero]] with your [[Hunter]] [[Hero Power]].
 
It might vary depending on whether your Hero is [[Rexxar]] or [[Alleria Windrunner]].

====Swipe====
 
{{lv|Patch 3.2.0.10604|2015-10-20}}
 
[[Swipe]] works in 2 steps and therefore causes on-damage triggers to activate in this order (after all damage has occurred): The minion targeted, then all other minions in reverse order of play. The spell should work in 1 step and on-damage triggers should run in the order of the minions being played.
 
 
[[Blizzard]] works in 2 steps and will cause the new minions spawned by Imp Gang Boss and Grim Patron to also be frozen (but undamaged). It is currently clarified that this is not a bug, and that "the damage and freeze are separate events". This was not changed in [[Patch 2.7.0.9166]] (Tavern Brawl patch).

====Total Turns====
 
{{lv|Patch 2.7.0.9166|Tavern Brawl patch}}
 
The game ends after turn 89 and before turn 90, giving Player 1 a slight unintended theoretical advantage. After turn 89 fully ends and just before turn 90 begins, the game ends in an unconditional draw.

====Totemic Slam and Justicar Trueheart (Combo)====
 
{{lv|Patch 3.1.0.10357|Mech War Tavern Brawl patch}}
 
If you use [[Totemic Slam]], you click a 'choose one' card, which counts to the game as clicking on a card. Then, [[Combo]] effects of cards such as [[Eviscerate]] are activated this turn.

====Totemic Slam and Justicar Trueheart (interactivity)====
 
{{lv|Patch 3.0.0.9786|TGT patch}}
 
Player reports that he attacked with [[Maiden of the Lake]], [[Dr. Boom]], clicked [[Totemic Slam]] and then ended his turn (presumably without selecting a totem). Afterwards, his Hero Power remained visually exhausted when his next turn began (but the opponent still saw it as usable). Because his prevents him from using it, this is also a gameplay bug.

====Tracking====
 
{{lv|Patch 4.0.0.10833|LoE patch}}
 
[[Tracking]] doesn't trigger draw-based effects. Therefore [[Chromaggus]] does not trigger when Tracking is played. No card is generated by Chromaggus.

[[The Mistcaller]] buffs the cards in your deck at the time of drawing them. So if you played [[The Mistcaller]] earlier and use Tracking, the picked card won't get the enchantment of The Mistcaller, because it was not drawn.

====Trigger ordering (dominant player)====
 
{{lv|Patch 2.8.0.9554|TGT pre-purchase patch}}
 
When a game of Hearthstone starts, one player has PLAYER_ID 1, and the other has 2. This is unrelated to who goes first/who gets the coin.
 
 
When ''triggers'' from both players trigger simultaneously, they are queued not in strict [[order of play]], but for the dominant player (PLAYER_ID = 1) first, then the second player's. Each player's triggers are queued in minion age order. When ''events'' (such as deaths/damage/healing) are queued simultaneously, they are resolved in global order of play as expected. The bug only affects ''triggers''. This bug notably does not affect Deathrattle triggers, because Deathrattles are triggered within each death ''event'' which are already in the correct minion age order.

(It also exists for on-damage triggers and probably every kind of trigger in ''Hearthstone''.)
 
 
====Trigger ordering (force play)====
 
{{lv|Patch 3.1.0.10357|Mech War Tavern Brawl patch}}
 
[[Deathlord]], [[Voidcaller]], [[Alarm-o-Bot]], [[Ancestor's Call]] and [[Varian Wrynn]] all have in common that they forcefully move a minion from your hand or your deck into play. They all also have a bug in common that the minion thus summoned is the oldest in the order of play, not newest, when considering simultaneous Deaths. The order of play is non-bugged when considering triggers, such as end of turn trigger order or on-Death trigger order, or when considering other Events, such as simultaneous Damage.
 
 
More specifically, for the purposes of simultaneous Deaths, their 'timestamp' (which is updated when an Entity is generated (including summons, effects like Gang Up or at the start of the game) or played) is not updated when force played for the purposes of simultaneous Deaths, but is updated for all other simultaneous ordering purposes.
 
 
* https://www.youtube.com/watch?v=jIqPtOOyjQ4 (shows behaviour of Gang Up - force played minion created by Gang Up has the timestamp of Gang Up being cast, w/r/t simultaneous Death Event ordering)

====Trigger ordering (simultaneous combat damage)====
 
{{lv|Patch 2.7.0.9166|Tavern Brawl patch}}
 
If 2 minions have "On Damage" triggers, and one of them attacks into the other, the defending minion's "On Damage" trigger always triggers first, followed by the attacking minion's trigger. This is unintuitive because in all other cases, simultaneous triggers happen in minion age order. This mostly matters if the "On Damage" triggers spawn new minions ([[Grim Patron]], [[Imp Gang Boss]], [[Dragon Egg]]) in the presence of [[Knife Juggler]]s.

====Trigger ordering (simultaneous AoE damage)====
 
{{lv|Patch 3.2.0.10604|2015-10-20}}
 
[[Swipe]] causes on-damage triggers to activate in this order (after all damage has occurred): The minion targeted, then all other minions in reverse order of play.
 
https://www.youtube.com/watch?v=TBv0-u3W4jQ
 
 
[[Explosive Shot]] causes on-damage triggers to activate in this order (after all damage has occurred): center, right, left. Same happens with [[Powershot]].

http://www.reddit.com/r/hearthstone/comments/39zrcp/patch_9166_gameplay_bug_changesfixes_swipe/
 
 
The correct ordering for all of the examples listed here should be from the oldest minion played to the newest minion played.
 
 
====Unearthed Raptor====
 
{{lv|Patch 4.0.0.10833|LoE patch}}
 
Sometimes, if your opponent copies a deathrattle minion with Unearthed Raptor, your client will disconnect from the server and you will have to reconnect. This has been observed with several different deathrattles.

==Fixed bugs==
 
 
===Non-gameplay bugs===
 
 
====Add friend dialogue====
 
The Add Friend dialogue box could become permanently stuck on screen, obscuring the Battlefield under it and preventing game interaction with the minions under it.

* https://www.reddit.com/r/hearthstone/comments/39tlpy/add_friend_window_bug/
 
 
It is unknown when this bug was fixed.
 
 
====Alt-tab====
 
The game window would minimize when alt-tabbing out of the game in windowed fullscreen mode.
 
 
This bug was fixed in [[Patch 2.2.0.7835]].
 
 
====Arena deck====
 
{{lv|Patch 3.1.0.10357|Mech War Tavern Brawl patch}}
 
[[Arena]] decks with multiples of a card would sometimes use more than one slot to list the card. For example if you had 3 [[Water Elementals]] it would list 2 Water Elementals, then separately below it a single Water Elemental.

====Back button (Arena)====
 
After you finished drafting your [[Arena]] deck, the back button became unresponsive. Workaround: Esc -> Options -> Credits -> Exit credits. This bug was introduced in [[Patch 2.8.0.9554]] (TGT pre-purchase patch).
 
 
It is unknown when this bug was fixed.
 
 
====Back button (quest)====
 
If you received your daily [[Quest]] right after you completed your match, the back button would become unresponsive. Workaround: Esc -> Options -> Credits -> Exit credits.

It is unknown when this bug was fixed.
 
 
====Classic packs====
 
Classic card packs in the [[Shop]] only displayed the "Best for new players" banner if the player has already purchased a pack that session.
 
 
It is unknown when this behavior was changed. Currently, it doesn't display the "Best for new players" text at all.
 
 
====Dialogue boxes====
 
Since [[Patch 2.6.0.8834]], the chat text and add friend dialogue boxes had text vertically misaligned within the typing area. This occured on all platforms, and was more pronounced at certain screen resolutions.

====Esc key====
 
Esc key was not working after you opened and closed your [[Quest]] log. It was working again after you went into any sub menu and came back to the main menu.

====Flavor text====
 
Spam clicking a card in the Collection Manager to bring up the flavor text box could make the flavor text box shrink.
 
 
This bug was fixed in [[Patch 2.4.0.8311]] (BRM patch).
 
 
====Hero "Thinking" emotes====
 
Heroes had been using their idling/thinking emote a lot more often than usual, even when a player has only just started his or her turn, to the point of annoyance.

====New cards====
 
If you opened a card that you already had 2 copies of and [[Disenchant]]ed all extra cards, it would still be listed as "new" in the collection.
 
* https://www.reddit.com/r/hearthstone/comments/3myu5f/annoying_bug_in_the_new_patch/
 
 
This bug was fixed in [[Patch 4.0.0.10833]] (LoE patch), but not noted in the patch notes.
 
 
====Payment information====
 
If you went to [[Arena]], clicked the "i" button on the bottom left and pointed your cursor above the "More" and "Cancel" buttons, you could hear the "Back" button sound and you could click it to go back to the previous menu.

===AI bugs===
 
 
====Doomsayer====
 
If a [[Doomsayer]] was silenced, the AI would stop playing minions, mistakenly thinking that the minion would die the immediate following turn. This could be used to defeat most AI and [[Adventure]] bosses.
 
* https://www.youtube.com/watch?v=phPj815Iig4
 
 
This bug was fixed in [[Patch 1.1.0.6141]] (a week after [[Naxxramas]] was released), but not noted in the patch notes.
 
 
===Adventures gameplay===
 
 
====Majordomo Executus (encounter) and Bane of Doom====
 
Using [[Bane of Doom]] as the killing blow on [[Ragnaros the Firelord (encounter)|Majordomo Executus]] would skip the [[Ragnaros the Firelord (boss)|Ragnaros]] phase of the boss battle on both Normal and Heroic difficulties.
 
* http://www.twitch.tv/trumpsc/v/4010690&t=1h53m46s
 
* https://twitter.com/bdbrode/status/586363413565046784
 
 
The technical reason is because a successful Bane of Doom acts as a [[Destroy]] effect, and the encounter was only programmed to expect death by Health loss.
 
* https://www.youtube.com/watch?v=Z7216jkhENw
 
 
This bug was fixed in [[Patch 2.7.0.9166]] (Tavern Brawl patch) by removing the additional [[Destroy]] effect when it hits a Hero only.
 
* https://www.youtube.com/watch?v=Xcnk9ndudXY
 
 
====Nefarian (encounter) and Bane of Doom====
 
Using [[Bane of Doom]] as the killing blow on [[Nefarian (Hidden Laboratory)|Onyxia]] in Phase 2 would skip the final phase of the boss battle on both Normal and Heroic difficulties. This was similar to the bug where using Bane of Doom on Majordomo Executus would skip the Ragnaros Phase of the fight.
 
 
This bug was fixed in [[Patch 2.7.0.9166]] (Tavern Brawl patch).
 
* https://www.youtube.com/watch?v=Xcnk9ndudXY
 
 
====Misdirection and Patchwerk (encounter)====
 
[[Patchwerk]] ignored [[Misdirection]] when attacking with his weapon. However, it was also stated that "The bosses of [[Naxxramas]] do not play by the rules. :)" although not specifically directed at this bug since certain cards are banned from use in some Naxxramas boss encounters. There was currently no confirmation from Blizzard that this bug is intended behavior.

====Rock Out and Unbound Elemental====
 
In the [[Garr]] encounter, using [[Rock Out]] did not cause [[Unbound Elemental]] to trigger and grow in size if a player managed to obtain them.

===Golden card bugs===
 
 
====Chromaggus====
 
When a non-golden [[Chromaggus]] copied a golden card, the copy was non-golden. When a golden Chromaggus copied a non-golden card, the copy was non-golden.

====Effigy====
 
{{lv|Patch 3.1.0.10357|Mech War Tavern Brawl patch}}
 
Since patch 3.1, using a non-golden [[Effigy]] created golden minions.
 
* https://www.reddit.com/r/hearthstone/comments/3mwwd7/odd_effigygolden_card_interaction/
 
 
This bug was fixed in [[Patch 4.0.0.10833]] (LoE patch), but not noted in the patch notes.
 
 
====Gang Up====
 
# Using a golden [[Gang Up]] on a golden minion would cause 3 golden cards to be visually shuffled into the deck. The drawn cards were golden.
 
# Using a golden Gang Up on a non-golden minion would cause 3 non-golden cards to be visually shuffled into the deck. However the drawn cards were golden.
 
# Using a non-golden Gang Up on a golden minion would cause 3 golden cards to be visually shuffled into the deck. However the drawn cards were non-golden.
 
# Using a non-golden Gang Up on a non-golden minion would cause 3 non-golden cards to be visually shuffled into the deck. The drawn cards were non-golden.
 
 
(2) was a visual bug as the cards visually shuffled in should look golden. (3) was a bug as the copied cards that are drawn should be golden. This bug was officially listed in the "Known Issues" sticky on the Blizzard Bug Report forums with the text "Casting a Golden Gang Up on normal minions is not producing golden copies." but it is inaccurate.

====Mirror Entity====
 
Since the [[Patch 1.0.0.4217]] (10 Dec 2013 closed beta patch, this patch introduced the current ranking system and Test Season 1), a golden [[Mirror Entity]] will no longer produce golden minions. Prior to the patch, it did work correctly. Ben Brode has said this bug is on a very low priority to fix. The intended behavior is that a golden minion is summoned if either the target or the Mirror Entity is golden. Bug is still present in [[Patch 2.4.0.8311|BRM patch]].

====Missing concede sound====
 
Since [[Patch 3.0.0.9786]], you were able to concede before all of the queued animations had been resolved. In this case, the sound of your hero conceding would be missing.

====Secrets====
 
Since [[Patch 2.4.0.8311]] (BRM patch), whenever a secret would trigger, it played the ping-like sound effect twice, once before the animation of the secret being revealed, and once after the secret's effect has resolved.

===Spectator bugs===
 
 
====Choose one====
 
If the spectated player played one of the [[Druid]] cards with [[Choose One]] ability, the two cards would remain stuck on the screen until the end of the match. The temporary workaround was to exit to main menu and spectate the player again.
 
* https://www.reddit.com/r/hearthstone/comments/3a27na/spectator_mode_bug_introduced_with_the_new_patch/
 
 
This bug was fixed in [[Patch 2.8.0.9554]].
 
 
====Green cards and hero power====
 
If the spectated player ended the turn without using some of the cards or hero power, the green border around them would still persist and would update correctly only after you mouse hovered over them.
 
 
This bug was fixed in [[Patch 3.2.0.10604]] (2015-10-20), but not noted in the patch notes.
 
 
===History sidebar bugs===
 
 
=====Faceless Manipulator and damaged minions=====
 
If you copied a damaged minion with [[Faceless Manipulator]], the sidebar would show the amount of damage that was done to the minion.

However, if you copied a damaged minion that had less than or equal to 50% of its remaining HP, the sidebar would show that it died.

This bug was fixed in [[Patch 4.0.0.10833]] (LoE patch), but not noted in the patch notes.
 
 
===Visual-related gameplay bugs===
 
 
====Area of effect spells====
 
Spells like [[Consecration]], [[Starfall]], and [[Lightning Storm]] that cause the screen to shake would not return the game board to its original location. The resulting board location was either shifted up or down slightly. With repeated casts, this resulted in players being able to view less and less of his hand, or the opponent's hand, depending on which direction the board shifted. Listed to be fixed in the BRM patch notes, but the bug was still not fixed.
 
 
This bug was fixed in [[Patch 2.7.0.9166]] (Tavern Brawl patch), but not noted in the patch notes.
 
 
====Choose One and aiming at your hand====
 
If you took a Choose One effect with a targetter like [[Wrath]] or [[Keeper of the Grove]] and clicked on your cards with it, they would get displaced from their usual location and angle. To fix the bug, you had to rapidly click slightly under the UI element that was showing your current Mana Crystal amount. The cards would remain oddly angled but become playable.

====Gang Up and Choose One ====
 
If [[Gang Up]] was used on a minion with [[Choose One]], it would visually display 6 or 9 cards entering the player's deck instead of 3. Only 3 actual cards entered the deck.

====Nozdormu and transform effects====
 
Transforming [[Nozdormu]] via effects like [[Tinkmaster Overspark]], [[Polymorph]] or [[Recombobulator]] would cause the sandstorm effect to remain for the remainder of the match. This was purely a visual bug, turns no longer last 15 seconds (See [[#Nozdormu|Nozdormu timer bug]]).
 
 
This bug was fixed in [[Patch 2.7.0.9166]] (Tavern Brawl patch).
 
 
====Rend Blackhand====
 
Whenever you played [[Rend Blackhand]] and cancelled his [[Battlecry]], a white glow where the legendary animation had been would stay on your board.

====Rope (End Turn)====
 
If you ended your turn right when rope started to roll out, the rolled rope image would stay on your screen for the remainder of the match.

This bug was fixed in [[Patch 4.0.0.10833]] (LoE patch), but not noted in the patch notes.
 
 
====Sludge Belcher (animation)====
 
The [[Sludge Belcher]] would take about 3 to 4 seconds to die (the animation) before the [[Slime]] was created and became targetable by the player. While not truly a bug, Ben Brode tweeted that the long death animation was a bug and will be fixed. This affected high level tournament gameplay where players would often spend the entire turn thinking and only start playing cards when the rope starts to burn. Ben Brode has commented that "Learning when you need to start acting is part of the game" in response to asking if card animations can be made not to count towards the turn timer.

====Spell Damage====
 
New to 3.0, when your opponent has [[Spell Damage]] +1 and plays a spell that does damage, the card text is not modified to show the new amount of damage. Your own cards that are modified by Spell Damage +1 still work as intended.

===Gameplay bugs===
 
 
====Alarm-o-Bot and Doomsayer====
 
If [[Doomsayer]] and [[Alarm-o-Bot]] are played in that order, at the start of the next turn, Doomsayer triggers first, followed by Alarm-o-bot. Since death is not checked for until all triggers have resolved, both succeed in triggering, and a bugged Alarm-o-bot card is returned to hand. If the player tried to play the bugged Alarm-o-bot from hand, it did immediately on entering the Battlefield. This is similar to the [[#Vaporize_and_Freezing_Trap|Vaporize and Freezing Trap bug]].

====Auchenai Soulpriest====
 
If [[Auchenai Soulpriest]] was used to flip healing into damage on a minion, on-damage triggers would not run. For example, [[Circle of Healing]] dealing 4 damage would not trigger [[Acolyte of Pain]]. This bug was introduced in [[Patch 2.7.0.9166]] (Tavern Brawl patch).
 
* http://us.battle.net/hearthstone/en/forum/topic/18132604497
 
 
This bug was hotfixed a few days later.
 
 
====Baron Rivendare and Earth Shock====
 
If [[Earth Shock]] was used to kill a minion with [[Deathrattle]] and [[Baron Rivendare]] was on the board, the Deathrattle of that minion still triggered once.
 
 
This bug was hotfixed on 15 August 2014, about 10 days after the Military Quarter of Naxxramas was released (this wing released Baron Rivendare).

====Bear Trap====
 
[[Bear Trap]] could activate on full board. Confirmed as a bug by Ben Brode.
 
* https://twitter.com/bdbrode/status/641456430248144897
 
 
This bug was fixed in [[Patch 4.0.0.10833]] (LoE patch).
 
 
====Burrowing Mine====
 
Exploded in hand (if obtained by [[Thoughtsteal]]) when next player had drawn a card, or the original [[Burrowing Mine]] was drawn. Unclear what was the triggering condition.
 
* http://www.reddit.com/r/hearthstone/comments/2ynrs9/if_you_thoughtsteal_a_burrowing_mine_it_explodes/
 
 
It is unknown when this bug was fixed.
 
 
====Cogmaster====
 
[[Cogmaster]]'s passive ability stopped working if its Attack and Health were swapped by [[Crazed Alchemist]], [[Reversing Switch]] or [[Polarity Shift]]. This is likely because its [[Aura]] was incorrectly programmed with a Priority higher than all [[Enchantments]], meaning that it was always processed first and the reversing enchantment overwrote the effects of the aura.
 
 
This bug was fixed in [[Patch 2.2.0.7835]].
 
* https://www.youtube.com/watch?v=1Gri691KO4g&t=2m40s
 
 
====Coldlight Oracle and Secrets====
 
If a [[Coldlight Oracle]] or [[Vaelastrasz the Corrupt]]'s Hero Power ([[Essence of the Red (Normal)|Normal]]/[[Essence of the Red (Heroic)|Heroic]]) forced the player to draw cards, and one of the cards is a [[Secret]], if one player took [[Fatigue]] damage, the game would hang for the player with the secret card revealed from the deck mid-draw. The concede option would not work and the player had to exit the client. This could happen on both [[Play mode]] and in [[Adventure]] mode.

====Counterspell====
 
When [[Counterspell]] was triggered (you can be the owner, triggerer or a spectator of either player), if you clicked away the big 'Counterspell' card that appears telling you what [[Secret]] was triggered, it was very likely that your client would hang and you needed to disconnect and reconnect to the game to resume playing.

====Darnassus Aspirant====
 
If you played a 0 cost [[Darnassus Aspirant]] at 10/10 Mana, the [[Battlecry]] made you have 9/10 Mana.
 
* https://www.youtube.com/watch?v=u3L50eGC0ug
 
 
If you played Darnassus Aspirant at 10/10 Mana but it cost 2 Mana, the behaviour was as expected, you went to, and then stayed at, 8/10 Mana.

This bug was fixed in [[Patch 3.1.0.10357]] (Mech War Tavern Brawl patch), but not noted in the patch notes.
 
 
====Deaths caused during "end of turn" effects====
 
An [[Imp Master]] on 1 HP died at the end of turn even if a [[Healing Totem]] was on the board. [[Kel'Thuzad]] resurrected itself if killed by [[Ragnaros the Firelord|Ragnaros]] at the end of turn.
 
 
The above were confirmed to be bugs because all "end of turn" effects should resolve before any deaths are checked for.

This bug was fixed in [[Patch 2.0.0.7234]] (GvG patch).
 
 
====Demonfuse and Sense Demons====
 
[[Sense Demons]] could draw [[Demonfuse]] as one of its two cards. This is because Demonfuse erroneously has the [[Demon]] racial tag, which is meant to only be on minions (and [[Lord Jaraxxus]] the Hero). Confirmed as a bug that will be fixed by Yong Woo here.

====Divine Shield and on-damage triggers====
 
 
If a minion with a [[Divine Shield]] took damage from a non-combat source, on-damage triggers would run. This bug was introduced in [[Patch 2.7.0.9166]] (Tavern Brawl patch).

This bug was fixed in [[Patch 3.0.0.9786]] (TGT patch), but not noted in the patch notes.
 
 
====Drakonid Crusher and Charge====
 
When [[Chromaggus (boss)|Chromaggus]] (encounter) played [[Charge]] on a fresh 9/9 [[Drakonid Crusher]] with the player at or under 15 HP, it got buffed to 14/9 instead of 11/9.

* http://us.battle.net/hearthstone/en/forum/topic/17086220506
 
 
It is unknown when this bug was fixed.
 
 
====Echo of Medivh====
 
If [[Echo of Medivh]] was played while the player controls a minion with [[Choose One]], the game would desync from the server, freezing for the player.
 
* http://us.battle.net/hearthstone/en/forum/topic/15699092639
 
 
This bug was fixed in [[Patch 2.4.0.8311]] (BRM patch), but not noted in the patch notes.
 
 
====Echoing Ooze and transform effects====
 
If you played an [[Echoing Ooze]], then transformed it the same turn via effects like [[Tinkmaster Overspark]], [[Polymorph]] or [[Recombobulator]], the green semi-transparent goo visual effect did not disappear and permanently remained on the Battlefield in the position of the original Echoing Ooze for the remainder of the match. This was purely a visual bug. This bug was introduced in [[Patch 2.0.0.7234]] (GvG patch).

This bug was fixed in [[Patch 3.1.0.10357]] (Mech War Tavern Brawl patch), but not noted in the patch notes.
 
 
====Echoing Ooze and Velen's Chosen====
 
If [[Velen's Chosen]] was played on an Echoing Ooze, the buff was correctly cloned at the end of turn. However, if either Echoing Ooze was returned to the player's hand via effects like [[Sap]], and that Ooze was later played again from the hand, the new Ooze would retain the sparkling animation that is standard for minions with [[Spell Damage]], but this was only a visual bug. However, when the new Ooze was cloned at end of turn, the clone would actually have Spell Damage +1, sparkle, and actually affect the player's spells.

====Faceless Manipulator and Frozen Champion====
 
When you tried to clone the [[Frozen Champion]] during the [[Sapphiron]] encounter, the game server would stop responding.
 
* http://us.battle.net/hearthstone/en/forum/topic/15538644159
 
 
It is unknown when this bug was fixed.
 
 
====Faceless Manipulator and Velen's Chosen====
 
When you buffed [[Velen's Chosen]] on a minion which has [[Spell Damage]] (e.g. [[Azure Drake]]) and cloned this minion with [[Faceless Manipulator]], the newly created minion would only grant you 1 spell damage instead of 2.

* http://us.battle.net/hearthstone/en/forum/topic/16202921242
 
 
It is unknown when this bug was fixed.
 
 
====Fallen Hero and Immune effects====
 
[[Fallen Hero]] extra damage bypassed [[Immune]] effect. If you had a Fallen Hero in play, a [[Mal'Ganis]] to make your Hero Immune and used your [[Hero Power]] on yourself, the base damage was prevented but the added damage by Fallen Hero went through.
 
* https://www.reddit.com/r/hearthstone/comments/3i500j/bug_with_malganis_and_fallen_hero_when_jaina_hero/
 
* http://tieba.baidu.com/p/4104346870
 
 
It also worked with [[Ragnaros (hero)|Ragnaros]]' Hero Power.
 
* http://us.battle.net/hearthstone/en/forum/topic/18710644804
 
 
However: Fallen Hero and [[Ice Block]] Immune worked correctly.

This bug was fixed in [[Patch 4.0.0.10833]] (LoE patch), but not noted in the patch notes.
 
 
====Fatigue and Replacing your hero====
 
New bug in patch 3.1.0.10357, replacing your [[Hero]] would reset [[Fatigue]] damage to 1. It worked with both [[Lord Jaraxxus]] and [[Ragnaros_the_Firelord_(hero)|Ragnaros]] (from [[Majordomo Executus]]).
 
* http://us.battle.net/hearthstone/en/forum/topic/19136833743

This bug was fixed in [[Patch 4.0.0.10833]] (LoE patch), but not noted in the patch notes.
 
 
====Feign Death and Added Deathrattles====
 
If you casted [[Feign Death]] and had on the field a friendly minion with both a [[Deathrattle]] and an on-Death [[Triggered effect]], the on-death triggered effect would go off once for its own 'feigned death'. It would not go off for other minions with Deathrattles. To do this, you had to play a minion such as [[Scavenging Hyena]] or [[Flesheating Ghoul]] and add a Deathrattle such as [[Ancestral Spirit]] or the Brawl effect of [[The Masked Ball]]. This was a bug because Feign Death is meant to only trigger Deathrattles, not on-death Triggers, and wdoes not, for example, count as a death to [[Kel'Thuzad]] either.
 
* https://www.youtube.com/watch?v=W52xmRRgvdU
 
 
This bug was fixed in [[Patch 4.0.0.10833]] (LoE patch), but not noted in the patch notes.
 
 
====Flame Leviathan, Living Bomb====
 
[[Flame Leviathan]] and [[Living Bomb]]'s area of effect damage, if you managed to trigger two or more in the same Phase, stopped affecting minions that have been reduced to 0 or less Health.
 
* https://www.youtube.com/watch?v=rdx5WpFuRYM
 
* https://www.youtube.com/watch?v=zYNWKSr-jqM
 
 
This was in contrast to other forms of area of effect damage, such as Explosive Sheep, which continued to damage all targets regardless of current Health.
 
* https://www.youtube.com/watch?v=QCk4CBuVnsM
 
 
This bug was fixed in [[Patch 3.0.0.9786]] (TGT patch) but not noted in the patch notes. As of 3.1, all-character AoE damage includes mortally wounded characters and all-minion AoE damage ignores mortally wounded minions.
 
 
====Frothing Berserker, Auchenai Soulpriest, Divine Shield====
 
Normally, a [[Frothing Berserker]] does not trigger on damage reduced to 0, such as by a [[Divine Shield]]. But if you used an [[Auchenai Soulpriest]] and hit a Divine Shielded minion with a heal inverted into damage, the Frothing Berserker triggered once.
 
* https://www.youtube.com/watch?v=PA40IjxYUJI
 
 
It also appeared to happen with other on-damage triggers such as [[Acolyte of Pain]].
 
* http://us.battle.net/hearthstone/en/forum/topic/14395499457
 
 
This bug was fixed in [[Patch 3.0.0.9786]] (TGT patch) but not noted in the patch notes.
 
 
====Hobgoblin/The Mistcaller====
 
Under unknown circumstances, a minion buffed by [[Hobgoblin]] or [[The Mistcaller]] could become immortal at 0 Health. This was not a visual bug - the Server would send you actions involving it, you could attempt to attack with it and fail (it moved a bit then the Server sent you your next set of actions, and it was still selectable), it took up space on your board, you could target it with spells and both you and your opponent would see it. The minions it had been observed with were [[Echoing Ooze]], [[Haunted Creeper]], [[Micro Machine]], [[Novice Engineer]] and [[Argent Squire]] (and possibly more). However, an Echoing Ooze was usually on the board at some point in the past.

====Joust====
 
When playing a [[Joust]], the jousted cards have their entity IDs revealed and can therefore be tracked when they move to the hand.
 
 
This leak have been hotfixed 2 times in total on 09/04/2015.
 
 
====Lightbomb====
 
If you played [[Lightbomb]] and any 0 attack minions were on the board, [[Spell Damage]] +1 bonuses were applied ONLY to them. If there were no 0 attack minions on the board, everything got the Spell Damage +1 bonus damage, as expected.
 
* http://us.battle.net/hearthstone/en/forum/topic/18704211721?page=1#19
 
 
Also, Lightbomb was dealing its damage simultaneous rather than one at a time (with on-damage triggers applied in between), so the [[Frothing Berserker]] vs Lightbomb bug should have been fixed with this change.
 
 
This bug was fixed a week after [[Patch 3.0.0.9786]] (TGT patch) came out and the behaviour of Lightbomb was reverted. Now we have the Frothing Berserker + Lightbomb bug once more.
 
 
====Mimiron's Head====
 
If you played [[Doomsayer]], [[Alarm-o-Bot]], [[Mech]], [[Mimiron's Head]] in this order (with another mech in hand), the [[V-07-TR-0N]]'s animation wwould play in the background and once he spawned, the game would hang. Each player had to reconnect in order to continue playing.

This bug was fixed in [[Patch 4.0.0.10833]] (LoE patch), but not noted in the patch notes.
 
 
====Misdirection and Noble Sacrifice====
 
[[Noble Sacrifice]] caused the game server to stop responding if it was triggered at the same time as [[Misdirection]]. Noble Sacrifice must have been played first then Misdirection so that they would trigger in that exact order. The reverse order was not bugged.
 
* https://www.youtube.com/watch?v=lJ0xtvynBVo
 
 
It is unknown when this bug was fixed.
 
 
====Misdirection and Stealth minions====
 
[[Misdirection]] did not trigger if you attacked using your Hero into the enemy Hero if all minions on the board were in Stealth. If there was at least one minion not in Stealth, Misdirection would trigger correctly and is able to redirect to any minion, including stealthed ones.

This bug was fixed in [[Patch 3.1.0.10357]] (Mech War Tavern Brawl patch), but not noted in the patch notes.
 
 
====Nat Pagle and Cabal Shadow Priest====
 
If a [[Cabal Shadow Priest]] takes control of an enemy [[Nat Pagle]], the fishing animation incorrectly plays on the opponent's deck when triggered.

====Old Murk-Eye and Grimscale Oracle====
 
[[Old Murk-Eye]] and [[Grimscale Oracle]]'s auras stopped working after [[Aldor Peacekeeper]] and [[Crazed Alchemist]] effects, for a similar reason as Cogmaster's aura was bugged with [[Reversing Switch]] - the aura was coded to go before, not after, enchantments, and was thus suppressed by this direct attribute setting enchantment.
 
 
This bug was probably fixed in [[Patch 2.2.0.7835]], but the exact date is unknown.

====Ram Wrangler====
 
Minions put into play by [[Ram Wrangler]] would always spawn to the far right.

This bug was fixed in [[Patch 3.1.0.10357]] (Mech War Tavern Brawl patch), but not noted in the patch notes.
 
 
====Recombobulator and Emperor Thaurissan====
 
A minion that had its casting cost reduced by [[Emperor Thaurissan]] would recombobulate into a minion of cost equal to the reduced casting cost. This actually crashed the game on the server side if [[Recombobulator]] was played on a [[Molten Giant]] that had its cost reduced by 1, because there are no minions that have 19 casting cost.

====Rumbling Elemental====
 
For a week after Rumbling Elemental was released, if you played Faceless Manipulator targeting a Battlecry Minion, your Rumbling Elementals triggered twice in the After Play Phase, instead of just once.

This bug was hotfixed about a week later.
 
 
* https://www.youtube.com/watch?v=gRWmVzANWD0
 
 
====Resurrect====
 
If Player 1 had no dead minions since the start of the game and Player 2 did, if Player 2 played [[Resurrect]] (this one would function correctly), any subsequent Resurrects played by Player 1 while his dead minions list would remain empty would instead resurrect a minion from Player 2's list of dead minions.

====Return to hand effects====
 
If [[Stalagg]] or [[Feugen]] was returned to hand (from the Battlefield) and failed to do so because the player's hand is full (10 cards), then it would instead die and trigger its [[Deathrattle]]. Blizzard has clarified that this is [http://us.battle.net/hearthstone/en/forum/topic/12675248374 working as intended]. But, such a death by bouncing to hand was not recorded by the game, so when the second one dies later (by any means) and its Deathrattle is checked, [[Thaddius]] is not summoned. This is verified to be a bug.
 
* http://www.youtube.com/watch?v=56tLx26t1Iw
 
* http://us.battle.net/hearthstone/en/forum/topic/14580767961#5
 
 
[[Kel'Thuzad]] did not resurrect minions killed by returning to a full hand, despite their Deathrattles triggering.
 
* http://www.reddit.com/r/hearthstone/comments/2fs5gp/kelthuzad_freezing_trapsap_bug/
 
 
This bug was fixed in [[Patch 2.4.0.8311]] (BRM patch), but not noted in the patch notes. It is also tested that [[Resurrect]] will correctly consider minions killed by returning to a full hand.
 
 
====Sacred Trial====
 
When you play [[Repentance]] or [[Snipe]] and your opponent plays [[Lord Jaraxxus]], these Secrets trigger on Lord Jaraxxus the Hero and have their expected effect.
 
* https://www.youtube.com/watch?v=n8u2Senk_XU
 
 
This is because they are hard-coded to work this way. Normally the Secrets can only trigger on minions.
 
* https://twitter.com/bdbrode/status/532326185305243649
 
 
When you played [[Sacred Trial]] and your opponent played [[Lord Jaraxxus]] while having 4 or more minions on the board, Sacred Trial triggered, targeted Lord Jaraxxus the Hero but had no effect. To be consistent, it should either trigger and destroy Lord Jaraxxus the Hero or not trigger at all.
 
* https://www.youtube.com/watch?v=GE8xQJDuodA
 
 
This was hotfixed about a week after [[Sacred Trial]] was released. Now Sacred Trial kills Lord Jaraxxus the Hero.

The effects of [[Savage Roar]] used to be unable to be silenced off. The minions retained +2 Attack even after silencing them. This bug did not occur with [[Bloodlust]].

====Shadow Madness and Silence====
 
 
If you used [[Shadow Madness]] to take control of an enemy minion, copied it with [[Faceless Manipulator]] and [[Silence]]d all copied minions, they would all return to your opponent's board and could bypass the 7 minion limit if your opponent's board was full.

[[Shadowflame]] could target your own [[hero]] starting from [[Patch 2.0.0.7234]] (GvG patch). Doing so will cause the player to lose the game immediately.
 
 
This bug was fixed in [[Patch 2.4.0.8311]] (BRM patch), but not noted in the patch notes.
 
 
====Shadowflame and Spell Damage====
 
When [[Shadowflame]] was used on a minion with 0 Attack, Spell Damage would fail to increase the damage.

====Snake Trap====
 
If your board was full, [[Snake Trap]] would still trigger when one of your minions was attacked and produced no snakes. This was inconsistent because [[Noble Sacrifice]], [[Mirror Entity]] and [[Spellbender]] would not trigger if your board is full. However, an argument could be made that this was because Snake Trap had the potential to offer partial value (0 to 3 snakes), while the other secrets were "all or nothing" value.

====Swipe====
 
When [[Swipe]] was used on [[Imp Gang Boss]], it would deal 4 damage to the Imp Gang Boss, causing a 1/1 Imp to spawn, then deal 1 damage to all other minions, including the newly spawned Imp which proceeded to die. This was clarified to be a bug.

If Swipe was used on a [[Grim Patron]] with more than 4 HP, it would deal 4 damage to the Grim Patron, causing a new Patron to spawn. 1 damage was then dealt to all other minions including the new Patron, causing another Grim Patron to spawn. If the original Grim Patron was 3/10, then the result was three Grim Patrons with 3/6, 3/2 and 3/3 HP in that order from left to right.
 
 
This bug was fixed in [[Patch 2.7.0.9166]] (Tavern Brawl patch), but not noted in the patch notes. However, Swipe still triggers on-damage triggers in this order: The first minion hit, then all other minions in reverse order of play.

[[Explosive Shot]] is confirmed to deal damage in 3 phases (center, right, then left). Suppose the enemy has 3 Grim Patrons on the board, in the order A, B, C from left to right, and all 3 of them are buffed to 3/10 for the purposes of this example. If you cast Explosive Shot on B, B first takes 5 damage and spawns a Grim Patron (D) to its right. This new Patron D then takes 2 damage and spawns another Patron (E) to its right. Then Grim Patron A takes 2 damage and spawns F to its right. The result is A, F, B, D, E, C which are 3/8, 3/3, 3/5, 3/1, 3/3, 3/10. It is not confirmed if this is a bug.

====Sylvanas Windrunner====
 
[[Sylvanas Windrunner]] could potentially steal a dying minion, caused [[Kel'Thuzad]] not to resurrect them as they switch sides.

====The Skeleton Knight/Anub'arak and Baron Rivendare====
 
{{lv|Patch 3.0.0.9786|TGT patch}}
 
[[The Skeleton Knight]]/[[Anub'arak]] with [[Baron Rivendare]] and 9 cards in hand causes the repeated [[Deathrattle]] to discard itself from hand.

====The Skeleton Knight and Twisting Nether====
 
If you played [[The Skeleton Knight]] then [[Twisting Nether]], The Skeleton Knight might have experienced a visual glitch and turned invisible in your hand. This would make him unplayable.

====Vanish====
 
Since the [[Patch 2.4.0.8311|BRM patch]], playing [[Vanish]] sometimes caused the server to stop responding and the player was unable to proceed with the game, play any cards, or even concede. The player had to exit the application and attempt to reconnect to the game.

This bug was fixed in [[Patch 2.7.0.9166]] (Tavern Brawl patch), but not noted in the patch notes.
 
 
====Vaporize and Freezing Trap====
 
If a player has both [[Vaporize]] and [[Freezing Trap]] in play in that order, when an enemy minion attacks the hero, Vaporize will trigger first and mark the minion with ''pending destroy'', then Freezing Trap will trigger and return the "dying minion" to hand. When this minion is played later, it dies immediately on play. This is similar to the [[#Alarm-o-Bot_and_Doomsayer|Alarm-o-bot and Doomsayer bug]].

* https://www.youtube.com/watch?v=YthDmzNagU0
 
 
Note that Freezing Trap is well known not to trigger on ''mortally wounded'' minions, such as when an [[Explosive Trap]] trigger first before a Freezing Trap.
 
 
This bug was fixed in Patch 3.1 or 3.2, but not noted in the patch notes. The minion will be bounced to your hand, but when re-played will no longer be considered ''pending destroy'' and will survive.

====Velen's Chosen====
 
Since the [[Patch 2.4.0.8311|BRM patch]], if [[Velen's Chosen]] was played on an enemy minion, the caster of Velen's Chosen still gained the [[Spell Damage]], rather than the owner of the enemy minion. This usually happened when Velen's Chosen was redirected by [[Spellbender]], or if the player used Velen's Chosen to buff [[Moira Bronzebeard (Heroic)]], or a buffed minion gets stolen.

This bug was hotfixed on the servers around 2 weeks after the BRM patch, but the fix was not noted anywhere.
 
 
====Voidcaller====
 
[[Voidcaller]]'s Deathrattle used to ignore the board limit of 7 minions if a [[Baron Rivendare]] was on the board.
 
 
This bug was hotfixed on 15 August 2014, about 10 days after the Military Quarter of Naxxramas was released (this wing released both Voidcaller and Baron Rivendare).

====Voidcaller and Doomguard====
 
If you were holding a [[Doomguard]] card above the Battlefield while a [[Voidcaller]] died, if the Deathrattle caused that Doomguard to be selected to enter the Battlefield, the Doomguard would get put into play slightly below where the mouse cursor was instead of the correct position in the Battlefield. Depending on where the position of that Doomguard is, it may become uninteractable with.

This bug was fixed in [[Patch 3.1.0.10357]] (Mech War Tavern Brawl patch), but not noted in the patch notes.
 
 
====Vol'jin====
 
If you played [[Vol'jin]] while you had no minions and all enemy minions on the board were [[Stealth|stealthed]], he entered play as a 6/0 without requiring you to select a [[Battlecry]] target and instantly died.

This bug was fixed in [[Patch 2.4.0.8311]] (BRM patch).
 
 
====Warsong Commander====
 
Starting from the [[Patch 2.0.0.7234|GvG patch]], [[Warsong Commander]] did not grant [[Charge]] to summoned minions, only played minions.

This bug was fixed in [[Patch 2.4.0.8311]] (BRM patch). However, the patched behavior is not the same as the original pre-GvG behavior in that it no longer gives Charge to minions that would be buffed beyond 3 [[Attack]] by [[Battlecry]] effects, such as the [[Bloodsail Raider]] and [[Blood Knight]].
 
 
====Wilfred Fizzlebang====
 
[[Recombobulator|Recombobulating]] a minion reduced to 0 Mana by [[Wilfred Fizzlebang]]'s effect would summon another 0 Mana minion. The intended behaviour is that all mana cost related enchantments are removed when a minion is played from your hand.
