I have some very bad news. The Sims 3 is rife with glitches and bugs, and I have lost more than one family to this. When I tried to play tonight, my UI had disappeared and so had Addie. To be specific, Addie had turned into a little glowing white spiky ghostlike ball, which then disappeared after about ten seconds. I can still navigate with the mouse, and keyboard shortcuts still work... so while in theory I could still play this game, the utter lack of UI makes it practically impossible. My other saved game works fine, but Addie, Toby, Eddie, Nathan, and Shaun are lost, perhaps forever.
I've done some googling on the subject and the issue seems to lie with the World Adventures expansion pack. After returning home from a vacation, sometimes sims disappear or the UI disappears. It doesn't affect everyone, so apparently I'm one of the unlucky few -- though we're not that few, because it seems pretty common. Unfortunately, the general consensus of various sims 3 gurus and forums and help pages is that the problem is not fixable. I tried restoring the backup file of the neighborhood, but that didn't work. I will try a complete uninstall and reinstall of the game, but frankly, I'm not hopeful.
If I can't restore the family, I will start over from scratch with a new sim. I hope I don't have to do that, but in case I do, I hope you, dear reader, will give the new guy (I've already decided it will be male) a chance.
