I had issues with the Sims 3 with the KeynLockes. The Sims 3 kept on dropping all my store bought content, including worlds.
So, the KeynLockes are no more. But, I wanted to use some store bought content, and went hunting. I found a back up of a backup of the Sims 3 game files and when I went in, the store content remains, so I'm now playing with that.
I'm returning to the Citrus family and playing them in Sunset Valley.
