Now, here's the question: why encrypt offline saves?! Who and why would this be needed?! But even if someone needs it, that's not the point; the point is that it would be better to make this a separate option. What's interesting is that the mod didn't even ask me for a password when saving the game, so where am I supposed to get it now? I don't mind spending time testing this game, but I think it's very illogical.
Update. It turns out to be even more interesting: single-player autosaves (for scenarios) are not password-protected.
There was also one strange case where, when a hero leveled up, the cursor was invisible and only appeared at the edges of the game window.
