Problems started, when I've downloaded and installed Heart of Death mod. Enabling it made game freeze at first loading screen, before main menu. When disabled this mod, game worked fine. But I wanted to play this mod and started looking for a solution.

I've used BOSS to sort load order. Didn't help. So I've disabled this mod again and now game still freezes at first loading. I thought that BOSS messed up something, so I've restored old plugins.txt. But game is still freezing. Weirdly, when disabling Osuro's Overhaul master file in Wrye Bash, game runs fine. But I've installed nothing related to OOO last time.

It looks like game has broken in magical way.

I didn't do anthing when installing HOD except using BOSS. What's happening?
