Does not work Thomas...
Looking at your pictures this is the case,
you have the glitched Skin tones. The only way to actually fix it is to change your Sim Detail till it changes back. You say you did it and it didn't work: did you save and exit the game after changing that option? If not, you need to otherwise the changes won't occur.
EDIT: Just though I should explain what I think this glitch is - What happens is that in CAS the Sims skintone is far paler than what you set it to be, or it should be. What AdnaanA is trying to show is that in their game it shows the skin funny but then in what I presume is the Wikia picture it is normal. AdnaanA, am I right in assuming the skintones return to normal when not in CAS?
