[HSY] Prom disappears from Calendar

Hello,

I’m someone who really loved The Sims 4 High School Years pack, especially because of the prom interactions. However, at some point, all prom-related interactions completely stopped working.

Prom does not appear on the calendar anymore, and when I click on Sims, there is no prom-related interaction menu at all. Even if I bring a prom sign and place it on the lot, the only interaction available is “Throw Away.”

Additionally, when I click on school lockers, the only option is “Claim Locker.” Mischief interactions only work with the whiteboard—other prank interactions involving lockers, toilets, etc. do not appear at all.

The only thing that still works is gathering with friends before prom. But when the actual prom time arrives, all the other Sims suddenly disappear without any notice. Even if I travel to the auditorium, nothing happens. Naturally, applying for prom is also impossible. Sneaking out through the window interaction does not work either.

I’ve tried uninstalling and reinstalling the game, removing all mods, and even starting a completely new save file, but nothing has worked. I really want to enjoy the High School Years pack, so this has been extremely frustrating.

The “Friendly Invitations” option is properly enabled in the gameplay settings as well.

Please give me back my High School Years experience.
