Sim disappeared after marriage with NPC
One of my sims (played character) disappeared suddenly after marrying an NPC. I've left the household the sim belonged to as unplayed for a while and when I went back to pick the storyline up again, he had apparently married and disappeared. Now I cannot find him (or his partner for that matter) anywhere, not even in the Manage Households tab.
How can I recover this sim and add him (and his partner, there's space for both in the family) to the original family again? I'd hate to have lost him forever.
If you at any point saved them to your library you can get them from there.
