Unplayed Households Disappearing
After the Life and Death update, I created a new save file and downloaded a bunch of sims from the gallery as NPC's. I've noticed recently that some of these NPC households have disappeared. I do have aging turned off but I've never had an issue with NPC households being automatically culled and new NPCs are still spawning. Only a week had passed in game when I noticed a particular NPC had disappeared and was no longer in the game. I've only seen ghosts culled in my game in that short space of time.
I've seen a couple of similar bug reports (the last about 3 months agao) but they don't exactly match the issue I'm having and apparently there was a fix for one of those issues in a recent patch that only affected new saves. I've never had the error code 800. I do have UI Cheats Extension mod installed, which I always keep updated.
Is this a bug or are my NPCs just being culled now?
