The Player Spawns below the Ground lvl and keep taking falling dmg till death again.
Its an endless circle.
How to reproduce:
Move the HUB to a higher lvl, when you die now (before the game is rehosted or saved),
you will get this bug.
How to Fix as Player:
Reload a Game where another player is alive, and let him move the HUB back
to a lower or same lvl then before.
