I noticed that when I went into the nether, I generated in the middle of netherrack. So I started mining to get out of the little box I was in, but then I needed to quit the game. So I quit and came back to work on my world. But, I spawned INSIDE of netherrack, so I started suffocating, and I was nowhere near my portal
