I'm Playing H3C on a single random map. My city Forest>Hero Ivor>other random all and other options 8 players(HN\AI) hardest difficulty with cheat for infinite movement.
After first turn i got that my hero in castle doubled(seems like moved) and when I tried to move it I lost my starting centaurs. Blessed Elfs stayed. After a few weeks I got grail and after upgrading my starting city with it. I had to stay for a few days near my other city(no camp option on). I pressed end turn. and my hero moved in time of tan(brown) player. started attacking some creatures.(with my in-battle control.) And after it started moving by 2 steps in both directions near mapseller. And here i lost my control of the game. Have to ALT-F4.
Any suggestions on how to fix this bug? or How to avoid it?

My PC WIn10x86Home(laptop)

And another one in campaign and random maps sometimes game crashes to desktop without errors. I remember there was crashing in original heroes even for win7 so it's not so big problem. As it is.

Several crashes are fixed in the HD mod, see if your performance improves with it.

Thanks for the answer and the links. I'll try it. But I played earlier HD+ modded WOG3.58f and to me it's not so good as it should be.
Maybe I'll try again and see what happens. Thanks again.
