Hello @itsmejoy7
These links explain about culling.

I know this is an older thread, but something I recently noticed when I came back to playing my game

Outdated/obsolete CC/Mods caused some of my sims to disappear - Once I removed the CC that was causing the issue, my missing sims returned and haven't been a problem since! It took a bit of trial and error to find the actual content that was the source of the problem, but a couple of reloads of a older save meant that I was able to resolve the issue and bring back the missing sims!

I posted about it on this thread

Yesterday I started the 100 Baby Challenge. By midnight my sim had 7 kids. This morning when I went to play, all the kids were gone, and all her relationships were gone. The only evidence that the kids even existed are the beds that they slept on. Is there a way to get my sims back?

They might be taken away by a social worker due to neglecting if you were playing the other household and left that family unplayed. But, if not, I am not sure.

I see you are new to the forums so you may be new to the Sims as well?
Are you sure you saved your game?
