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

Good evening!
I guess my questions belong here:
1. In the game, some characters are displayed as gibberish instead of normal symbols. How can I fix this? Could it be that I installed something incorrectly?
2. The autosave function doesn't work when launching the game through the HD launcher. What could be the reason? (saves are not created).
