Bukkit

I am getting the following error in console at start up. http://pastebin.com/JcBiCskQ
  I have a local dedicated machine, that starts the server on boot.

I get the following error in console after clicking join sign. http://pastebin.com/u7YUs4Dt
  I am not TP'd to the arena, but am stuck, in front of the sign, just like you would be at game start. Required a /sg leave command.

After a /reload command (Needed: /sg reload) I get no errors, and the join signs work as intended.

I am also getting leftover dropped items in the arena on next game join.
