After much tinkering with .xtbl files I have restored the muscle and fat sliders to something resembling normal while keeping the breast sliders as excessive as the level 2 expansion. Anything more excessive is easily possible but I'm not going to do it because it causes problems with the mesh. Essentially the player model is not detailed enough so anymore expansion causes things to become... polygony. http://www.mediafire.com/download/4sneq6waiwtom23/Character creation.zip
