For the past week, I haven't been able to even open the game. It continues to reload constantly. I was ****** and ready to delete the game but I thought I'd do everything I could to try to fix it. I noticed that after every reload, I could see one of my sims for like 2 seconds before it would reload again. I noticed that this particular sim was in a neighbors house. I thought maybe deleting all my party boat friends would work. I went to the Game Center and unfriended all neighbors I had from the sims. IT WORKED INSTANTLY.
I opened the sims and it loaded like it should and was fine! I was so happy that it was fixed. I wanted to share this in case anyone else is having this problem, this is what worked for me! Try it before deleting your game.
