I have no idea what causes it or how to reproduce it, I just know that it happens. I will attach a video and if I absolutely have to I can upload my world to Drive but it's huge so I'm trying to avoid doing that. My world is really strange, I think it got corrupted in some snapshot (mostly dark chunks and structures spawning in the wrong biome) so maybe that caused it along the way.

I found another spot in my world that won't accept bone meal which is in the main base area I live in. I am attempting to Optimise my world in order to see if it fixes it and will leave the results here.

After optimising, nothing has changed. Still unable to use bone meal in those areas.

The world download link provided no longer works. Please update the link if you can, or at the very least, provide the seed and coordinates of a location where this occurs.

Hi there. This seems like a case of MC-264155. Could you please verify is that is the issue you're experiencing here?

I was able to find that this is the same issue. It was a survival world so I had no way of knowing it was cave air, but I used the replace function of the fill command in a copy of the world to confirm that it was cave air. So yeah it's a duplicate of MC-264155.

How the cave air got there when both spots are above ground is another question, but clearly a separate bug.
