What happened?

I'm consistently falling through the world when I join and I when I respawn I'm still 1 inside a block.
Must be some coalition calculation issue.

Maybe also threading because I have 32 core.

Also, sometimes it spawns you 2 or 1 block(s) inside the ground.

I think it's because the chunk generation or something is faster and makes it so you don't fall because the client hasn't gotten a chunk yet and is assuming all air.
