When I export my CC3 characters to Unity 2019.3 or 2019.4.  The bones get messed up - they become stretchy, tall and slim.  I attached a screen shot.  If I re-import, it is fine but if I disable the "Auto-Processing" when I'm deleting the jaw bone (to fix the open mouth issue), it does this to the rig.  Any help would be appreciated. I attached a photo to show how it is making my model look like Slender Man.
