I always check sqrs before repairing for exactly that reason. It’s a relatively simple solution, if annoying. There is still the problem of ppl coming up and stealing the item youre repairing, however… This is especially painful when someone goes and trolls like this at SK. You drop your weapon to repair it, someone steals it, and you cant kill them OR finish SK. It’s never happened to me before but I get paranoid AF everytime I have to repair there.
