It was an error. A big error, but an error no less. They have to prove you stole stuff. We got sued once because we mistakenly entered a unit for a work order and then they took us to court claiming stuff was missing. The judge understood that it was an error and that nothing was stolen and we didn’t have to pay a dime. Document everything and have your employee go into court with you if it goes that direction so the judge can see that it was a mistake and all items were moved, not stolen. Good luck
