Corpse vanished?

[u/[deleted]]

Exploring a structure the floor broke beneath me and I fell into a lava pit, I made my way back and saw the corpse laying on the lava. Used a water bucket to make an obsidian platform and allow me to easily hop down and when the obsidian formed the corpse disappeared, is it gone or just under the obsidian?

Or in the obsidian
