MOST of the rock cliffs West of Kamyshovo have spots where if walk down the rock into a small crevice you will instantly die. You don't have to fall or get hit. You just slide down the rock and die. EVEN IF ITS ONLY A FOOT. It's a horrible glitch that makes sniping at that location not even possible anymore, I've died there TWICE thinking the first time was just a fluke. But there are multiple spots where this has happened and it's just so retarded to spend so much time to get geared up only to DIE to a stupid glitchy rock surface.
