I think so haha. At first 3 out of 5 sims had blank pictures and were unplayble. I saved and reloaded to no sims at all on the panel and completely grayish-blued out control bar.
Finally I tried going back to an old save but it pretty much just repeated what happened the first two times. I didn't travel or anything. Gen 4 was a chef so she was pretty much just making cupcakes and brownies all day after school.
