I was on a world about an hour and a half ago and clicked "Open to LAN" and right clicked my bed to see if I set spawn there, destroyed it and saw it placed only half of a bed. After recording it a bit, I stopped recording and left world and rejoined and died randomly. Saw I couldn't walk or interact with world. Got the recorded as well.
Dunno how to explain it quite well. If I may link, this is what I got.
