Short dirty nail swatch causing Sim to look metallic

After purchasing Enchanted by Nature my sim turns shiny, much like the skin overlay that was added. (Or they  actually look like one of those mimes out on squares acting like a golden statue that you can have your picture taken with for a small fee.) I have not added the skin overlay in CAS and this usually happens after I have played for a while, half an hour or so but if I restart the game it turns back to normal. It often happens when my sim is energized but not always. My sim is human, not a fairy if that matters. I have tried playing other old saves but it is not happening there, just the new one. I have a few mods but they have all been updated. (MC Command, TwistedMexis betterbuildbuy and UI cheats extensions.)

Another thing that also happens and this happens also only in the new save and straight away, not after playing for a while. My Sims gets all pixeled when I move the camera slightly away. It only happens to my sim, not the townies. I have a very high end gaming tower with a good graphic card etc. so I know that is not the issue. (Also as I said, just the new Enchanted by Nature save is affected.)
