After the December 17 patch he hip joint on the female human body is broken.
It doesn't matter which body type you use but try to equip any of the dancer bottoms and look from behind.
There is also errors with the texture down the thigh, with light reflecting in the wrong way.
Here is a pic of how it looks now: https://dl.dropboxusercontent.com/u/...4/hiperror.jpg
The bug weren't there before December 17 where the thigh were perfectly smooth.
