Black Gold Inf crash

[MonstraG]

I'm starting local co-op server on this map. Switching to RU side and start playing. In around minute after first contact between teams game crashes. Just closes, and window says something about closing PR.
LOL. Wanted to test this more. Tried again. This time coudn't switch tems - game forgot to load UI. So I stuck with a view of the map. Can esc, but nothing else. Oh. If I press LMB, it clicks. Like an unloaded weapon.
I don't even know how to write a bugreport about all this mess. Disconnected and started again. Same no-ui error. It's not even showing "loading menu" window.
