I first noticed it on a friend's character, and now I cannot unsee it! From the basic, no /cpose'd stance, it is #3 in the cyclable stances. On breathing in while in this idle stance, their hips glitch forward and then go back to their default position.

(sorry this one is huge! best way to show it off though.)

No other issues on any of the other stances, this is the only weird one I've seen.
