Playing a world created in 21w44a that I converted to 1.18 pre-release 1. One of the chunks in my village resets every time I reload the world. No other chunks seems to be affected as of yet and this only happened since upgrading to the 1.18 pre-release. Attached are screenshots of this happening, with debug screen up. Additionally, every time I load the world while standing in that chunk, I fall through the world for a second before the ground loads in, whereas this doesn't happen anywhere else in the world.
Seed is -83273113063622936, coordinates are in screenshot.
Here's a link to a video I took of this happening, uploaded on google drive. If this isn't allowed I can remove it. https://drive.google.com/file/d/1_u0ToUo6fiH2TR3FXIGgSpE1ru1YNfOP/view?usp=sharing

chests placed in earlier versions do not save correctly and revert to their pre-migrated-state every time the world loads. Critical: Item DUPE / Item loss.

After poking around a little more I've realized that the chunk doesn't necessarily regenerate completely, it just reverts to how it was when I first upgraded the world to 1.18 pre-release 1. In the affected chunk is a leatherworker's building, and prior to updating, I had removed the three cauldrons in front of it. Those do not regenerate on save and load, seemingly only changes made after the update are reverted to. On the subject of that leatherworker's building, the chest inside regenerates its loot on save and load as well.
You may be able to upload the compressed file to Google Drive (or another file sharing site), and send the link here.

Here's my world save. Let me know if it doesn't work, I'm not as familiar with file sharing via google drive.

the new pre build seems to have resol;ved the issue
can confirm it is fixed i tried moving everything like normal the chunk saved correctly thank you mojang for expediting this fix i hope you all have a wonderful holiday season
Similar issue for me. Mine's also a world created in 21w44a but nearly every chunk regenerates. I've used up an entire unenchanted diamond pickaxe digging a tunnel that totally vanished after saving and reloading. There's a wall near my spawn (part of a village) that I've torn down five times while testing this.
Seems that it only affects destroying original blocks, though. If I put down a piece of cobblestone and save/reload, it'll keep that, even if the wall next to it regenerates. If I move it, it'll stay moved.
Can upload my world on request if anyone wants, but I wanted to confirm this.
