Businesses and Hobbies interrupting Xbox gameplay

I recently downloaded the Businesses and Hobbies expansion pack. Since then I have been constantly receiving Error Code: 0 everytime I try to save and if my Sims travel from their home, all their furniture has disappeared when they come back. I really don't want to uninstall the add-on as it cost me literally fourty dollars, but I can't even play the game like normal. I have 5 other expansion packs, 4 game packs, and 1 stuff pack and none of them had this problem. I also have the Businesses and Hobbies pre-order content. I don't know why it's doing this. Does anyone else have this issue?
