Well a few actually. The first is concerning the Brotherhood of Shadow guys, they look nothing like the cutscenes, instead they look like darth revan except with white outfits. Another problem is in concerning Matilda, rather than being an evil looking Twi'lek, instead she is a Yoda looking character, basically just a different looking version of Vandar actually...I dunno why it turned out that way but it just did....Also I'm not sure if he's to look this way but...the guy in the Korriban cantina you meet, Drix Keliwt, he also looks like a version of Revan with white appearance. Is this suppose to happen? Let me know.
Most likely, you're using other mods that modify your appearance.2da. If you have other mods that modify/add appearances, the appearances that the Brotherhood of Shadow mod may be affected.
I'd recommend reinstalling your mods, (after cleaning out the override folder).
