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

I'm on Xbox console.   

My Sim was working on her presentation at Darby's Den then she went home.  When I tried to send her to do her presentation, it wasn't in her inventory.  I tried what was suggested by others by emailing her professor for a status report, but still no presentation board. 

HOWEVER when I go into build mode at Darby's Den, her presentation board IS THERE!  But it disappears in live mode. 

How can I get the presentation board back so it's either visible in live mode at Darby's Den OR get it into her inventory??
