Signs of Corruption

@xxnearlyperfectx -That's exactly how things went in my save where Claire Ursine's baby was taken by the social worker after she died and it started after the baby got taken away and things got worse until I had sims in wrong-aged careers like elders in elementary school and toddlers in high school or adult careers.Nobody was in the right aged careers after that save started getting corrupted.It sounds like you've had a child taken away from one of the town's families in your game and that can cause a save to become corrupted.I had three of them corrupted from that social worker situation.
@karritz -That workplace failure can be either a glitched rabbit hole which means replacing the rabbit hole or a child got taken by the social worker and the save is becoming corrupted.Glitched workplace means deleting the old rabbit hole shell and replacing it to get the workplace working again though it can mean a corrupted save if nobody in town is staying at work or school to the end of the day or shift and others can't get to work.
