[NEEDS SAVES] [DU] Sim didn't receive presentation board/ Gone Missing

My sims are living in student housing in foxbury. Their presentation boards vanished after i put them in their inventory a little while later. Maybe after they went to class or commons. The next sim day i wanted them to present their board and that's when i noticed it was gone. All 3 of my 4 sims. I hate for my sims to get horrible grades. I have cc eyelashes and tank tops only installed. I have all packs and latest patch installed.
