Hi there, to cut a long story short. A player joined , not going to mention his name. But he said "I am going to crash your server". I just treated him like a normal noob / troll and ignored him, until the server unexpectedly dropped out. I instabaned him and his IP. http://pastebin.com/TZvvxRzS The server error log came up with that, the server just completely locked up. He joined teamspeak about 60 seconds later, and for some reason decided he would tell me how to do it. He explained that it was something to do with stacking 2 powered beacons on top of each other, then placing TNT mine carts on the top. I think this may have just been some kind of distraction or something to try and get himself off the hook. Thats all i know. I am going to be testing this extensively.
