I hate to be a nuisance, but what exactly is group.catche?
Some of my sims are bugged, and I was wondering if that was causing the problem. The Swain guy in the University expansion won't even do anything on his own, along with the other male roommates, without some queue coming up that say "delete, reset, or cancel." I have tons of hacks/mods but they are updated with freetime, so I'm not really sure whats causing it.
