Why did The Sims 3 travel, the villain disappeared, and the character bar and lifetime expectations were blank?

There is a bug in the archive. I tried it and it was very unpleasant. Don’t save it. If you don’t save it and go back, there shouldn’t be any problem. There may also be an error in the mod or file. If the mod still has no effect after deleting it, it may be really dead and I have to get another one, which is very unpleasant. At that time, it became editing a city or something, selecting a family, and I ended up going to China to select a family. . Yes, my little people disappeared out of thin air. If you can't solve it, let me give you a better reason: their plane crashed on their way back.
