Unfortunately this crashes my server. There seems to be some incompatibility with Towny.
Before it crashes the player gets barrated with "[Towny] Not allowed to Destroy in the wild." messages. Apparently the random teleport needs to destroy something in a protected area, which Towny denies so often that the server crashes.
