Beds don't set spawn point.

Whenever I sleep in any world, the "respawn point set" message shows up in the chat, but if I die later, I get sent back to the world spawn.

Last time this happened, I slept on a beach before going diving, but I was killed by a drowned while building an underwater base. Instead of respawning on the beach, I was sent back to the world spawn and ended up losing all my items due to the long trip.

Please fix this bug, it makes it impossible to have fun in the game now.
