Hand of Fate. Part 1: On the March

I looked at this unfortunate situation. 20 nomadic centaurs. Passing level 21. Characteristics: 34, 25, 12, 17, 9, 5. There was no save before his turn. And I always take my time – I like to explore every detail, and I hadn't even figured out how to get to the ship yet. Here's a save file near the brown area. And, I apologize, I searched through the game folder. Strangely enough, I downloaded it as version 3.1 (and intentionally looked for this specific version), but the installed version has 3.0 written in the txt file. It seems the problem lies in this. Can you tell me where I can download version 3.1? I already have 4 versions of Heroes 5, and it's not certain that I'll download the correct one again.
