Sometimes, when i open inventory (doesn't matter I open the bag by TAB, or i want to see contents of the box/corpse), the game stops, no sound, picture doesn't move anymore, no reaction for mice and keyboard. Then game process just closes. No any crashreport windows, unfortunatelly.

I couldn't find a pattern. For example, i can open and close the inventory 10 times, for 11 time the game will freeze and crash. Or i use inventory many times in battle, and in any of iteration of using inventory game stops and crashes.
