Todays Patch made several sims change skin colour.

All of a sudden after patching, my co-workers and some townies are sporting a brand new skin tone, But when I check them in CAS they look normal.
Is it just me? No, I'm not running a vanilla game atm, so I haven't had the energy to remove all mods and clean the game and report an official bug report. Thought I check to see if it's a general patch problem first. I don't have any elaborate mods though, just MCCC, UICE and a fe simple mods. Nothing that messes with genetics and appearance.
