I've got a weird problem that recently cropped up. Whenever I'm seen by an enemy now my toon goes into a sneak mode non sneak mode toggle. If I'm in 1st person, it appears that I just look hard to the left and then back forward every couple of seconds or so. If I'm in 3rd person, my character just stands up and squats repeatedly. It pretty much makes the game unplayable since I can't aim a gun. Anybody seen this or know what could be causing it?
