Mod requests (orders).

Together with the scenarios (which are separate from the mod and located in the maps folder), it weighs twice as little.

I launched a mission on your mod, made a couple of moves, and it didn't crash.

You don't have the entire current version of my mod with all the modules from it. Neither does my wife. I shouldn't have changed anything critically important that would cause a crash specifically on this map. Although, I don't know. I'm not a jack-of-all-trades. I don't know everything about modding, and I don't understand everything about it.

My wife has everything working with all my packs. It seems something is wrong with my saves. I'll try replaying mission 4.

The reason has been found. It's the new resource models from Might and Magic Heroes VI and Might and Magic Heroes VII.
