I've downloaded a lot of Sims off of the Sims exchange and I've installed them all with the game launcher. When I play the game and create a Sim, all of the Sims have the same hair style and not the hair style they're supposed to be. Also, some of the Sims look discolored. One girl who's supposed to have white skin has really really back skin. Does anyone know how to fix this. I have all of the Sims 3 expansions including the latest late night one.
