@spritelst Sounds like something a combination of MCCC settings that I'm familiar with could do, but it's supposed to happen only if the Ghosts have been released to the netherworld (Cleaner > Neighborhood Cleaner > Clean Culled Sims). You can exempt Sims related to active family members, but I don't think that covers all played households, just the current ones (Cleaner > Neighborhood Cleaner > Bypass Family Ghosts). I think it could also be worth heading to Deaderpool's own support to make sure that your MCCC settings aren't set up in a way that makes it happen again, as it does seem like it could be MCCC-related - those Sims were already dead, so Neighborhood Stories shouldn't be able to re-kill them. There should be MCCC flags you can set to prevent it, for example, or a combination of settings to avoid.
You might try loading earlier versions of the save to see if there's a pre-culled version if you want to keep those particular ghost family members.
If the folks over in Deaderpool's support tell you that MCCC couldn't have done this, please do come back and let us know.
