Player character, hangs up when you brush up against a rock or boulder(sticks to rock), under water and on land. and it seems to happen mostly on the right side of my character, when i brush up against a rock with my left side it does not get hung up as much. Iw you wiggle the mouse it frees you up. I am hung up in the screenshot. It happens more under water.
Edit:
I just tried it on the beach on rocks and my foot got stuck, on my left side. I added that screenshot also. {F18784} {F18785} {F18786}
