Internal Server Error When Player Exits Game and Lack of Warp.

[ZandercraftGames]

Description
When clicking on the sign to go to the arena, the player receives the items to play the game, but is not teleported to the arena world. The player is then kicked for an Internal Server Error if they run /kill to escape from that partial in-game state.

ERROR Stacktrace
The following error occurs immediately after the player runs /kill and is what kicks the player from the server:
