I tried looking around in the forums and searching but couldn't find the answer to my question. I want to reset my Alpha Server, not go back to an old back up or anything, like generate a new untouched map, whats the easiest way to do this?
On the Server properties file, edit world-name to anything else but World. It'll generate a new world.
If by reset you mean just stopping the server and starting it back up go to the server console and type STOP and press enter. Then start the server.
