I read some other threads on a similar topic but they were all quite old so I'm starting a new one.
In a long-running game, I have three brothers that were populating the town with their blueboos. I just noticed that some of the blueboos are missing, however. Two, to be precise, from two different households, the children of two different brothers. Each one was a twin, and their twins are still present in the houses. The children show up in the relationship panel and family tree, but they are not in the houses. I've tried resetting them individually as well as resetSim * to no avail. I checked Edit Town just to make sure, and they are not in the households there either. I am now saving under a different title and I'm going to close the game, restart the computer, and check to see whether that fixes it. Otherwise I'm at a loss. They're not crucial to my game or anything, but just letting babies disappear goes against my nature.
If you can help, please do. I will update this thread after the game saves, quits, and re-loads.
