This is a repeat of a repeat. voting down because there are many many other threads covering this

This is true, i've seen others doing it, and i even did it myself, and its very very easy, you then can handcuff "yourself" or kill it to get the duped items, it's a very important bug. One that sould be fixed ASAP.

BTW: I haven't tested it yet in the experimental version, since it says in the config that spawns is now managed by the server itself (maybe this was a silent fix, to avoid people kowing it by reading the exp changelog).
