I\'ve tried searching, and found something similar but not quite the same.
In certain camera modes, non 1st person, the character movements seem to get stuck using the camera as a center point for turning, which causes the character to turn around the camera in a large radius circle instead of standing and rotating in place, this is really annoying.
To further add to the confusions... It does not do this all the time, and I cannot find a pattern to suggest what I did to make it occur. Though it seem to happen most if I run into combat, and change my camera mode while fighting.
