That extra info helped, thanks. It looks like this error came from the fact that the paperdoll wasn't in the game when this transformation was first added. It looks like I attempted to fix this, and the transformation works after the first time your hair changes, but when it changes the final time it bugged something out. It should be fixed with patch 0.47.5. The fix doesn't work retroactively, but you should be able to fix it yourself by visiting the Salon and just selecting the purple color and long hair style. (Salon is unlocked once you have over 60 femininity, and is under the town locations, if you didn't know. Sorry for the inconvenience.)
As for the eye color, that actually won't change. The way the expression system is set up requires for the eyes to be included, and the expression system can't account for different possible player appearances in the details of the expressions themselves, so hair and skin color work, but eye color does not.
