Subject: [PATCH] Prevent position desync 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.
