MCPE-169059When loading any chunk in the latest preview, they get visually and physically regenerated until they reload some seconds or minutes later. Once they properly load you will retain your position and every other stat, so your movement in these chunks does carry over.
This is deadly in worlds carried over from 1.17 or below, since world generation is completely different, you could be flying through plains and suddenly be suffocating inside a mountain, since the actual world would have a mountain there and the plains were just ghost chunks that hadn't loaded properly.In these ghost chunks you cannot use fireworks yet they dissapear from the inventory as if you did (Which is REALLY deadly in The End).
Placing and destroying a block wont yield any drops, but instead replace itself and a block above and below with air
That behaviour is similar to MCPE-167185, yet i couldn't find any mention of the ghost chunk issue, so im filing it separately.I believe the issue is that the game loads chunks from the seed data to ease world loading, but ends up messing up since the actual world might not be how the blank seed would generate, resulting in ghost chunks the player can freely move when they wouldn't be able to in the actual world.

Hi @magwar
Here is a copy of my world
https://drive.google.com/file/d/1XEDDcFWxo0wPmS3j7tBNfr4N5FLsWpOD/view?usp=share_link
But i dont really think there is a problem with it (well at least causing this haha, there is an unrelated issue because i downgraded it from 1.19 to 1.18 long ago using chunker and all of my old terrain now has no new generation below and its just void below y0 on most chunks, so dont worry about it)
This issue does happen in other and newly created worlds too. But since the world generation of every chunk in new world is the same as the seed since its... brand new, it's hardly noticed in new worlds. The only noticeable thing there would be that going into new chunks would replace blocks with air when trying to interact with them until it loads properly some time later.
Im sure it's something about the seed data and not some random generation issue because i know how my personal world seed would look with current generation, and the ghost chunks look exactly as if i were exploring them for the first time in newer versions, but it still could be something else, im just trying to provide as much information as i can.
(also, upon further testing and paying more attention, i've discovered this pretty much only happens the first time loading chunks after opening the world, but if you were to log out and log back in it would happen again, as if the problem was getting the chunk data in memory for the first time.
also also mobs bug out when stepping in these chunks, specially mounts like horses)
From what I've tested, this issue ONLY happens in preview versions, I've played every preview since i made this report and in every single one it happens.
I tested if it would happen on the latest releases (Will test again once 1.20 releases, but im sure it won't be affected either), and no, the game behaves normally, so i think this could be an issue with how preview builds are compiled or something?
