The barstool object (I mean the transparent object for your own custom stool, not the built in barstools) seems to be bugged. The angle in which the avatar sits on the stool seem to be pretty random. Or maybe related to which angle you're facing towards the stool before sitting on it. So for example, when clicking the stool and choosing sitting pose A you might get a random facing angle. Not at all related to the object angle in editor. It looks pretty strange when the avatar ends up sitting sideways on the stool.
Switch to pose B while sitting. Then switch back to pose A, and you most likely get the correct intended facing angle for the avatar.
It shouldn't be a big deal. But it looks pretty weird when people try to sit on the pose and end up backwards or leaning their hand out in thin air etc. I'm just wondering if this is intended by design or some sort of glitch or bug.
