@rosakwon Thanks for your report. I have merged your report with an existing thread about a similar issue where passive Sims disappear from the household.
Your Sim disappeared after being part of a Surprising Choice.
This is a known issue. The team is aware of it and investigating.
I’ve had an NPC I'd married to one of my Sims disappear overnight, including his relationship with my Sim. I hadn’t made her passive so that doesn’t account for it. He’s reappeared around town and she’s had to start a new relationship with him.
First time it’s happened to me, and at least it wasn’t one of my own Sims, but adding my voice to the others in the hope this issue gets fixed.
