I am running the plugin TNT Run on my server. I have created and finished three arenas: Overworld Arena, Nether Arena, and End Arena. (They were all created in the Overworld.) Sometimes, when I start the server, the console will generate an error that looks like this: pastebin.com/2JPpUD9M And then, when I warp to the TNTRun warp on my server, where I put the Join signs, the Overworld sign stays the same, but the Nether and End arenas say that they are Disabled in red letters. They aren't even disabled, I can join them! Can someone tell me what is causing this? Bump. I need an answer.
