Apparantly elevators are the most lethal thing ever. Had a party guest break the elevator on his way home, trapping everyone else upstairs. Repairs failed, electrocuting my sim, and disabling his ability to try to repair it further from that floor. Had to wait all night till the next day for the repairman to come, and by that time the pets were on the verge of being taken away due to hunger (Thankfully they had jobs and got fed there), my main sim was about to die, and one of the guests had already died. There were also....quite a few puddles.
