I've become a vampire with two different races, both female, one Nord, the other was Breton and both seem to have this problem with the textures, the NPCs have vampiric eyes, though mine just stay a normal brown, if I starve myself and use my invisibility power my eyes go black, but it's using a texture that isn't for eyes...It keeps reverting to the brown eyes, I've even got a vampire eye texture replacer to see if anything changed, it did not. So I am certain that my game is still using brown eyes...
Also, my character randomly has dirt on her face? Even though I chose no dirt, no warpaint or anything, I can go into "ShowRaceMenu" but as I move the dirt slider, nothing changes, same with make-up and such.
Another thing I noticed: Thief hood does not show properly on Breton Female on the player.
