I don't have a backup, unfortunately, I tried finding her again but she wasn't even on the list anymore. Makes me wonder why they are suddenly culled...
@bxbytrishx Sims can be culled for no apparent reason, although there may be some internal logic behind it. For example, the game itself will start culling when it thinks a world is overpopulated. However, it often misjudges—both the appropriate population and the actual number of sims—and it can keep culling even after the population has dropped below the target number. So it's often difficult to figure out what's going on, and maybe not worth the effort.
I've also seen culling of individual sims, not entire households but one or two sims within them, when the house doesn't have enough beds or is over the eight-sim default limit.
Unfortunatly, it sounds like your only options are to move on or to recreate the sim and use MC to repair the relationships. You can also assign a job and skill levels with MC, if that matters to you, and of course family funds. And you can use the genetics of your existing sims to create the replacement. I know it's not the same, but it might work for the purposes of your storyline. Let me know if you'd like help with that process.
