After the update i have noticed when i sat down or lay down on the ground, almost all my physbones are having a noticable jitter that i never had before, anything above 16 fps has this jitter, my avatars tails have a ground and a hip plane collider, those worked fine before the update. the other ones use normal physbone colliders. In the video u can see the jittering. As I do not own vr i cannot see if it also happens on vr.
