Good day, Mojang!

Your generation makes a little error.

Like: Floating Blocks, Cross, Borderlands, floating structures.

So while I was playing with my friend I asked was this floating, he said yes. Then I had to report the bug, nothing can float in irl(a.k.a In Real Life). So what are you using to; generate they/it made errors fix this. Thank you!
 

Steps to reproduce

1. Played a Minecraft World. 
2. Look around.
3. Check for errors 
4. I found a floating block/floating structure.

   Results
