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

Damn, this idea will never be tested. How long will this battle take in a quick match? :D

Send me the save file, and I'll take a look. :)
And maybe I'll remove the 30-round limit...

But then we'll have to come up with something to prevent an endless battle
or implement a way to interrupt a drawn-out quick match...

Added 24 minutes later

In the game on the new version, I got stuck in a castle, and the computer attacked me; the result of the quick match couldn't be undone.

Send me the save file.
And in general, if anyone has encountered this problem and has an up-to-date save file, please provide it.

I'll say it again: a save file with a bug that consistently reproduces is a million times more useful than any mention of the bug or a crash log.
