I have noticed issues with the avatar locomotion in 82.1, where avatars scaled smaller than 1x move quickly/erratically and skip the walk animation and go directly the the run animation state. The opposite is true of avatars scaled larger than 1x - they move extremely slowly, like walking through molasses. When the avatars are smaller I have also seen some random T-poses blip in after each run animation cycle. I would expect the animation to stay consistent and scale to the size of the avatar to maintain the same frame rate, but it seems that is no longer the case.
