I don't know why but Mirabelle at the winterhold collage is mostly invisible. Only her head shows and she's mostly bald. She's not the only one, the other chick is like that too. I thought it was all the women but that other apprentice shows up fine. What files to I need to delete or change to fix this?

Also, does anyone know of any good extra robes or robe re-placers? I use UNP body but if it's a full robe that usually don't matter.
