Well when I edit my character's body type the changes are not reflected in character creator and regardless of what I pick they always look the same in the plaza (outside of the main body type, which seems to work), I'm not sure I can convey that in a screenshot. The fact that the belly type keeps reverting back to "Round" suggests that none of the body shapes are saving correctly for some reason. I'll do more tests.
Edit: Butt seems to work, not sure about the rest. Belly is definately reverting back to round, regardless of what character I edit or make. And to be clear, when you go back to edit a character it will have "round" selected again regardless of what else you have picked before.
