[LD] Ravenwood: NPCs stand outside lot and don't come in

on ALL of my saves, my sims will greet the Ravenwood Welcome Commitee, invite them in, interact and befriend them, then once the event times out, they say "oh well, maybe next time!" then i immediately lose relationship points w them and it acts as if I left them outside the entire time. it's really annoying and happens every move and every save, if they even show up at all because sometimes no one comes. but when they do, this happens 100% each time.
