Hello,

I've been playing the latest snapshot on a server with some friends to test and play with the new features.

However seemingly at random some chunks start beginning to corrupt, if I do something in it which should change the data about that chunk (break block, place block, edit inventory of chests etc) and then relog all of the progress is undone as if I didn't touch that chunk.

It doesn't seem to just be limited to one chunk either I should note, it seems to happen in collections of chunks.

I built the world on snapshot 21w08b and have upgraded to 21w10a. I've had this problem on both snapshots.

For some reason this bug can seemingly also fix itself although I'm not sure what fixes it, it seems to be random. This is happening in both the overworld and the nether, I haven't yet tried the end.

I should also note that no errors appear in console either when logging in and out.
