I've been playing the Sims 2 for years, and I'm having a problem that's never happened before.

Even though I have free will on in game options, my Sims won't do a thing for themselves! I've tried switching between free will on and off, resetting game options, reloading the house--nothing works.

Has this ever happened to anyone else before? And if so, how did you fix it? I'd really like for my Sims to start going to the bathroom on their own again...
