Burglar: Recovered Stolen Objects Not Returned to Inventory

I'm fairly new to the game, only been playing for a few months, but recently my Sim was burgled, and after successfully fighting them off, I noticed two items disappeared and have not returned.  They're not in my inventory where in other games they have been found.  I have restarted the game a few times, and rebooted my Mac.  Any help is appreciated.
