(affects all versions) Probably not common but if you teleport to y= -30 million even in single player, you will be kicked. This happens in positive too but because you are falling, it isnt a big deal. If you tp to negative, you will always fall below -30 million and be kicked. And because you die in the void, this means you cant fly or tp away, and you cant respawn either because the buttons have a delay before they are clickable. The world is then lost as you cant spend more than 2 seconds inside it.
