With a second player (in multi) we noticed an animation bug when we are near a wrech (around 10 meters).
An anim, similar to leaning is repeating very quickly (maybe 3 or 4 times a second), even in water.
It stops when leaving the wreck area.
It also happens only the first time that u approach the wreck; when u get back and get closer again, bug does not happen.

Missions tested where a "free roam" (just two of us on the map and a chopper) and the mutliplayer mission Co-10 "Escape from Stratis".
