I have the same bug here. Due to this I constantly suffocate after placing beds next to a wall.
Also I don't respawn in my bed but at Spawn, even after I have successfully slept in a bed the night before.
Related to this, Wandering Traders also spawn on water and just Jesus hover there with their Llamas. 19w12b
Probably related to this issue. I converted my word to 19w03a and my sat down dogs were standing up and suffocated in the wall once i loaded into the world.
My animals (sheep, cows, chicken, pigs, turtles) and villagers are all not moving. I breed my chicken and the baby chick doesn't move either.
My cat teleports to me if i move to far away but doesn't change her position afterwards.
Iron golem, fish, zombies, spiders, skeletons and bats seem to move normally.
Same error here. I fell down the loading error in survival, but didn't die. Instead got teleported back up immediately. I can see a lot of mobs, they don't move but their heads glitch around very quickly.
19w13a , The world was loading fine in the last snapshot.
Also present in a newly created world.
Edit: With Local Multiplayer my friend can walk in chunks that haven't loaded for me, but I still can't access them. I can see him walking on air just fine. The chunks are always related to where in the world you load in.
