I had to exit the game when I did I was near lava but right next to it, when I logged back in, I was in the lava, then died instantly as if I only has 2 heart. When I respawned and went back to that location there was nothing there, I was expecting the situation like in a normal death when you die your stuff kind of spreads around where you died. I'm thinking maybe it spawn me a few blocks down or the 5 blocks over that would have been the very center of the lava pool I was near.
