I hit probably the most cruel Sims 3 bug ever.
My adoring couple's baby, Corben Dallas, had just made it to a toddler, when the family ran out of money to pay the bills.
The repo man showed up and started laughing maniacally as he sucked away random bits of furniture -- including the high chair in which the babysitter was feeding Corben.
With the high chair gone, our baby was left floating in midair, with no way to get him down!
Since The Sims usually encodes the logic for interacting with another Sim via objects (like the now-gone high chair), selecting any options like Pick Up, Play With, etc. just do nothing.
Now, Corben is screaming his head off as he slowly starves to death. I think even the social worker won't be able to take him away, since he can't be interacted with. Will I have an ex-baby on my hands?
