Gen 4 just aged up to YA and moved her spouse (Aaron) in and something went buggy with the move-in. First of all, when I checked his relationship tab after he moved in, the heir was listed twice, one version that was a vampire and that he was friends with (IE the one that moved him in) and another that was a stranger and not a vampire. The second one went away after a while so I figured I was okay.
Then just now I started up my game and tried to click on a door to change the allowed sims, and basically it's like the family no longer lives there. Clicking the door gives me the option to purchase property and when I mouse over the walls it shows the empty house icon. I cleared caches and restarted and it didn't fix the issue, and I also noticed that when I select that save it doesn't even show Aaron as part of the household.
Can I go back to my last save and try moving him in again?
