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

I'm on 2.98 - I don't seem to have any problems.

I don't have any problems on 2.98 either, except for crashes when right-clicking.

And the game runs very stably for me on 3.15. It crashes very rarely, only occasionally. Unlike the first versions of the third generation, which crashed every 2 minutes :D

Maybe Leader has some kind of system problem, a virus, or something else? Crashes don't seem to have a single explanation.

My system is fine.

Here's a screenshot of what's happening to me.

If you really want to help, do what I do. Attach the HD_CRASH_LOG text file. We'll bombard Baratortcha with them until the mod becomes completely bug-free :D :D
And screenshots are useless.
