I also encountered this bug on 1.14.60 on my 1 Year Old world.
I hope this and fall through world bug will be patched in 1.16.
[media]Also when I try to destroy the blocks they actually drop and the wall saves when I exit and reopen the world.
And sadly, after this bug, I tried to go sleep and then the game crashed. The crash deleted my Donkey 😞
I don't know why this bug is still not fixed. It's almost 2 years after creating this thread. I'm not playing on my Bedrock Edition survival world just because of this bug. I don't care if the FarLands/StripeLands will be deleted, I just want to play Bedrock Edition normally without worrying that I will randomly fall through the world, die and lose all my stuff. I want to travel around the world and find rare biomes ! Please try to fix that bug before the end of vacation 2020 ! We need to make this thread more popular !
