Ok, I have not got that error again, might have been a sloppy restart / updating without restart...
However, I still can't clean up peoples props by using the admin buttons, it said Patrik Swedman cleaned up MingeBags props but they doesn't get removed.
Another thing, one of my admins props didn't belong to him when he spawned them, they belonged to the world :S
EDIT:
Ok, every time I restart the map the UPS won't load, so every time I want to change map I have to make a full restart, and I have not updated it or anything this time :S
