I just built and tried to enter a nether portal in the nether but it wasn't transporting me so I relogged. When I came back I was suffocating underground near spawn, nowhere near where I was in the nether >:(
@phase The exact one? There's usually a 16x16 area of spawn chunks, and I guess you could call the exact one the one the spawn point is in. The spawn point is not necessarily in a certain position in a chunk.
> New players will initially spawn within a small area surrounding the world spawn point when the server is not in adventure mode. This area is 20×20 blocks by default (minecraft.gamepedia.com/Spawn)
