Attempting to walk over a log submerged in water has caused me to get trapped in the water, unable to move my mouse side to side (only up and down). My character is continuously slowly sinking into the ground and then popping up above the log when nearly fully underground.
Unable to vault or run, can crouch but not prone, and am stuck perfectly still repeatedly sinking and then popping back up. Very occasionally it will let me to do the standing vault, but won't move me at all.
I encountered this problem in the small pond / river northwest of green mountain at the new scout camp there.
