All characters were turned Aryan. All blonde hair, white skin, blue eyes. Karlach is a fucking nightmare. All popped back to normal when the game actually started but I legitimately thought I installed some Aryan Race mod on accident or something. Was desperately trying to figure out how it slipped past the Larian team onto their internal mod manager.
It's all the top-left options in the customization menus. It is really jarring, but then you just go edit them to how you like anyway.
