Rog, you're alot better than me by a long shot,
I changed several of the RLTranslateX, RLTranslateY & RLTranslateZ sections from the crouchState down and she still falls off the screen, my guess is I'm either missing one somewhere or you are using a different def.hap than I am, the one I'm using is called body_femaleDef.hap and it's from the body_female.htr that's 1.01mb. If at all possible maybe you can upload the def that you edited. Keep up the Great work.
