Hi! I may have found a fix.
My Teen sim lost his Prom interactions as well. Prom is still on the calendar but the prom category on interactions was not there.
I played a bit more and joined my Teen sim to a Career Day. My Teen sim traveled to the auditorium and then right after the career day, I suddenly got a prompt saying "Prom is happening on Saturday" bla bla, and all my prom interactions were back.
So maybe we just need to join an event at the auditorium to get the prom interactions back. 🙂
yes, mine disappeared as well, but it came back after I got the notification with prom tips, it comes a few times a week.
I have a theory that you can trigger this by asking another sim for prom tips. sometimes that interaction appears outside of the prom category
I was noticing this as well, it was earlier in the week and I had no option for prom. However, about midweek I got a message saying that prom was coming up and after I got that message it seemed like the prom options came back.
