I found this bug when I just joined the world and died. But when I should have spawned on my bed I spawned on the world spawn luckily I lived close to my world spawn and went to my bed to check it out. My bed's bottom portion hitbox was still there and I could break it and replace it. but I tried logging off and logging back in the same thing happened. So I'm kinda gonna stay close to world spawn until this bug gets fixed. Thank you devs, please fix
