The sit animation orientation is bugged to stay in the position the item was placed and not rotate when you change the orientation of the item.
This used to happen before occ due to lag, but would correct after a reset, so I waited until after a reset to post to make sure it was for real.
Noticed so far on the Chair2 and bench (small one) Sofas, regular and deco chairs are fine
Stools have you sitting off to the side of them
