Hm that doesn't happen for me.
I've just built a new Makashi breathing stance from Dragon, and I'll probably do the same for Juyo instead of recycling stock anims. Maybe that'll fix things.

Figuring out how to maintain upper torso while in walk anim at the moment. Gonna tweak the angle of the low guard and the offhand some more until animation flows smoothly.
