So, my avatars worked perfectly fine in the IK beta until about a day or so ago.

They use custom laydown/crouch animations, that worked just fine... however, suddenly, they are completely broken. The feet are placed way up above where they should be, and positioned like they're standing on solid ground. They "step" when I turn, as if the game thinks I'm 'standing' despite being prone.

This was not an issue a day or so ago, so clearly a VRChat update broke the IK again somehow.
