List of bugs (HotA)

This list contains all bugs and other issues that are still unresolved in HotA.

Name	Type	Description	Fix	Tested
Mechanic and Engineer's Breath attack against 2-hex units	Bug	When attacking a 2-hex unit from the middle hex above or below it, the fire breath follows the direction of the Mechanic's or Engineer's movement rather than the direction of the sword-arrow.	The issue remains unsolved.	1.7.0, Csaros (talk) 18:06, 25 January 2024 (UTC)
Starting experience	Bug	Heroes with default level 1 start actually having some random amount of experience in the double digits.		1.7.0, --Csaros (talk) 20:45, 25 January 2024 (UTC)
Disassembling combination artifacts in the hero exchange screen in allied multiplayer	Bug	If you're playing a game with another allied human player and go to the hero exchange screen you can disassemble an artifact like the armor of the damned from their hero's equipment thus crashing the game for yourself. I imagine that disassembling a combination artifact in another players backpack when it is full would also cause a game crash. In 1.7.1 hotseat, you can still disassemble artifacts in an ally's inventory, but it does not crash (only tested on empty backpack).		1.7.0, guest273 (talk) 1.7.1, 20:28, 20 August 2024 (UTC)
Fire Shield - Bad Luck interaction	Bug	Fire shield damage ignores Bad Luck effects. This issue is potentially intended, as it favours the Inferno town, who decrease enemy luck and have the only unit with permanent Fire Shield - Efreet Sultan.		1.7.0, Csaros (talk) 13:56, 24 February 2024 (UTC)
Earthquake bug	Bug	See the page - Seems like an AI defender can get bugged with repeated use of this spell.
Diamond Golem Adventure Map Sprite	Graphical	See Adventure map creature sprites: All neutral creatures face to the right, except for Diamond Golem.
Some Creature specialties calculated incorrectly	Bug	The game incorrectly calculates bonuses for creature specializations on some levels (e.g. Ingham at level 15)
Disguise not always working properly	Bug	v1.7.2 - After casting Advanced or Expert Disguise, troop numbers may be seen by the casting player as 0 when inspecting their own hero with right-click, but they will be seen by other players as 1-4... unless the other player casts Advanced or Expert Visions, which will make the numbers 0 again.
Quests can become un-completable	Bug?	The Seer's Hut (and Quest Gate/Guard) quests of 'Defeat a specific hero' or 'Defeat a specific wandering creature stack' can only be completed by the player that actually defeated the hero/creature. If that player is subsequently defeated themselves, there is no way to complete the quest. This is mostly noticeable on multi-quest chains (new to HotA) in Seer's Huts as an entire quest chain can be unable to be completed. Not sure if this is desired or not. Perhaps if the required player is defeated, either allow any player to complete the quest or just skip to the next step of the multi-stage quest?
Creature ability text for Catapult/Cannon incorrect	Bug	Depending on the skill level of Artillery/Ballistics, the creature ability text for the cannon/catapult automatically updates. However, at advanced/expert, it says that the cannon shoots twice, and at advanced it does not say the catapult shoots twice. This text can be seen when right-clicking on the cannon/ballista on the hero artifact paper doll (not sure if it is seen elsewhere).
Basic Resurrection no longer puts units at top of stack	Bug?	Wiki:"In Horn of the Abyss (1.7.2) with Basic Resurrection and no other resurrection methods, the number of destroyed creatures at the end of combat is the sum of losses throughout all phases of combat. In other words, the 'real' creatures are always destroyed first. If this would leave a victorious hero with no creatures then a single creature will survive (of the lowest level available type)." This was not documented in a changelog, although Resurrection was worked on in the very same patch. Originally the resurrected creatures were placed on top so you lose them only once if they get killed again. And I do not believe they would have made Earth Magic simply stricter requirement.
AI can buy juggernauts even if none are available to be purchased	Bug	Starting from week 2, AI can purchase juggernauts after taking over a town with their dwelling, even if the number of available units is 0. Gellissean recorded a video showcasing the bug. Further testing showed the number of units incorrectly available for the AI in week n, assuming growth g is (n-1) x g.	Solution remains unknown. The issue likely stems from the fact, that Gantry is technically a special building, not a creature dwelling in the town.	Gelissean, Francois Papyjama, Csaros (talk) 09:49, 14 September 2025 (UTC)
Dreadnoughts and Juggernauts don't take damage while standing in the moat if they use the Heat Stroke.	Bug	Both units seem to not take any damage from the moat, provided they use the Heat Stroke activated ability. Gelissean recorded a video showcasing the bug. * Is this a bug? Creatures casting a spell while standing in a moat usually DO NOT take damage (see the moat page). --Legate (talk) 13:06, 15 September 2025 (UTC)		Gelissean, 10:04, 14 September 2025 (UTC)
Statue of Legion incorrectly states component names in the map editor	Mistranslation	In the Map Editor, Statue of Legion is described to have the following components: Legs of Legion, Hips of the Legion, Torso of Legion, Arms of Legion and Head of Legion. The name Hips is incorrect - the artifact's name is Loins of Legion.	Editing the text in HotA.dat resolves the issue.	Csaros (talk) 09:12, 14 June 2025 (UTC)
