Teleport commands not working across dimensions (Build #81)

[BluXDragon]

Issue found on Dev Build #81 The commands "/spawn", "/warp", "/home", "/tp" do not work across dimensions.

eg. Player1 is in the nether, Player2 is in the overworld. Player 1 uses "/tp Player2". Player 1 will be receive a loading screen, and will be teleported to Player2's co-ordinates but not Player2's world. The loading screen appears regardless of teleport range, and chunks will reload.

Some times, during the loading screen, the player will be kicked with "Internal Server Error";
