Cant Change Skin Color

Im not totally sure what you mean there. But, here are screen shots. I had the game create a few random sims. As you can see they are all the exact same skin color.

And when I try to change it, the sim doesn't change.

Here, I tried to download a sim off of the gallery and the game actually automatically changes the sim to become this specific skin tone. (the hair disappeared because I don't have that pack. that makes sense)

You can also see what I was talking about the eyebrows in this picture. The pink ones I can edit but the brown ones are always there.

And hereto can see the grey underwear. That doesn't bother me so much but it appeared around the same time as the other issues so I wonder if they are related.

Hope that can help
