+Subject: [PATCH] Prevent position desync in playerconnection causing tp
+ exploit
+
+Caused the server to revert to the player's overworld coordinates
+after teleporting into the end.
+
+Sidenote: The underlying issue is that the move call can teleport
+entities and do other things like kill the entity. In the future,
+to fix all exploits derieved from this usually unexpected
+behaviour, we need to move all of this dangerous logic outside
+of the move call and into an appropriate place in the tick method.
