From my observations so far I've noted two issues:
Robe model 174, Suit. For all races and genders it seems to have lost its animation, and the lower part of the tailcoat hangs stiffly straight down.
Shadow Affinity. Does not seem to work for Shadowdancers. As Shadowdancer of level 5, I should be able to summon the next tier of shadow which is a Shadow Fiend, not a normal shadow. Then again, this could be working as intended and doesn't function for the PrC.
