Certain void worlds fail to spawn the player on the stone platform
The bug
When creating a superflat void world with certain seeds, the player is not spawned on the stone platform. This leads to them instantly falling into the void and dying. Respawning also fails to place the player on the stone platform.
To reproduce
Create a Superflat world with the Void preset, with the seed 4, 4710627461264753701, or 1929256340713261754.
