Last week my adult Sims got the opportunity to go away on vacation for 2 days, so I let them, leaving three teens at home with a baby. After the two days were up, the game said they were coming back in two hours, but they never did. I tried ResetSim, but it didn't work. I tried everything I could think of - evicting the household made the game crash, throwing parties to get in trouble made the police call them but they still didn't come back.
I'm pretty sure I know why this happened. The dad was about to age to elder, and he must have tried to while away. His portrait was weirdly replaced by his wife's picture, so there were duplicates of her.
Eventually I gave up and just enjoyed the challenge of raising a baby with just teens in the household, but now that they're grown up they can't go to University because "There are already adults travelling in the household". Even moving them out, without their parents, produced the same result.
I've pretty much lost all hope and I'm playing other towns now, but I was attached to that family and I'd like to fix them. Has this happened to anyone else? Do you know how to fix it?
I did have a pretty good laugh at the thought of the parents just staying on vacation fot the rest of their lives though
