HoMM3 HD is a mod (add-on) for the game Heroes of Might and Magic 3.

Vaflya, you are wrong. I hasten to dispel your misconception so as not to mislead others.

1. Critical bugs in the original game (leading to crashes and not affecting gameplay) are fixed by the main HD module; it will do this even if all HD options are disabled. (For example, the bug with rumors in the tavern causing random crashes, crashes in the city screen when clicking on the city icon in the list during the opponent's turn if they don't have that many cities yet, crashes in artifact merchants if there are empty slots between artifacts in the backpack, crashes if random creatures are assigned to a random hero in the editor, ...)

2. The NewerSoundLibraries option, which is enabled by default in HD, is specifically responsible for fixing critical errors when playing music in the original game (i.e., the errors are fixed by default).

3. A separate module, working independently of others, is responsible for automatically fixing map errors, such as duplicates, overlaps, etc., and is activated by the AutofixMap option (and deactivated by it as well). The AutofixMap option is always enabled by default in HD 3.x; if you want to disable it, you can always do so.

4. Only some critical errors (leading to crashes or freezes) in the original game are fixed by HD+, specifically those that affect gameplay: AI with an alliance of angels and neutral creatures in the army, casting the 'clone' spell, AI freezing (infinite turn). (all 3 for now)

5. If the module with the error is not _HD3_.dll, it does not mean that the cause of the error is not in HD. Moreover, if all of the above fixes are enabled, then the cause of the crash is 99.9% an HD error. (it is also true that HD sometimes exploits an original bug that is not exploited by the original game itself; such bugs are very difficult to catch, but ultimately the cause of the crash is still HD, because it does not exist in the original game.)

**

The main suspect for the source of the latest errors in the game (resetting RMG settings, timer, and crashes) is the 'fix' for desynchronization of new game settings among players in a network game, which is activated along with the TournamentExtensions option. In the next version, I hope to fix all this. But it may be necessary to sacrifice the fix for desynchronization in order to do so.
