Another bug, not sure if macOS exclusive – Setsuki will break like this and it carries over into gameplay. Seems like the mesh isn’t binding to the animation rig properly or something. Has happened at least 50% of the time but not sure how to reproduce (will create new thread if I find out how).
Setsuki’s model being broken is OSX-exclusive. If you go into training mode and pick Setsuki after launching the game, and she’s broken, she will be broken for all matches until you quit. If she’s not broken, she’ll be fine for all matches until you quit.
