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

I downloaded the latest 3.0 RC6 and started testing it. I began the "Armageddon's Blade" campaign. Everything was great; I liked the time saved by skipping the message windows when visiting locations, and the maximum number of creatures that could be hired at once... but then I made a mistake and decided to reload. However, since I hadn't saved: it was just a test, and I only had the Autosave file in the Games folder. And when I tried to load it, I got a nasty surprise: see the screenshot.
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.
