What I expected to happen was...:
After dying and leaving the world (without deleting it) I expected to see it when you join in it

What actually happened was...:
Then, after joining the world, I can't see it, also the blocks, entities, particles, but i can hear the entities (The only thing i can see is the sky).

Steps to Reproduce:
1. Die in Hardcore mode
2. Click spectate world
3. Leave the world (Go to the menu)
4. Enter the world again

The chunks doesn't load and is a big problem for someone who want to see his world after dying in this mode.
