So I play on this server that my friend JT owns. Another friend of mine, Lane, invited this 12 year old to the server and he has done things that we all don't like. He killed me and Lane, took our stuff, claimed the land so we cant access the chests, and isn't giving it back to us, and as it is right now, JT's computer is not working. So how can a server admin, override a land claim without the person's permission, without resetting the server and world.
