[MCPE-152656] Chunks are overwritten after update

I have a world since somewhen before Update Aquatic. After one of recent updates I had a crash with message that the world is corrupted. I reopened the world immediately after, and found that new terrain had generated over my build, replacing entire biome with river. Part of my build (bridge) was right on the edge of biomes and got distorted by blending. Hundred blocks to the left and to the right I have my old world with my builds, but the middle got overridden. My last backup with world intact is from November from the day 1.18 was released. I can provide a copy of my world if needed, with coordinates.

Yes, this is still happening in 1.19

I had tried updating the 1.17 world backup from November straight to 1.19.0, and had other random chunks corrupted with void wells or overwritten, even in the Nether. The world crashes with corrupted error after few minutes of playing.

I have tried updating it through Chunker, but I assume the same thing happens there too.

Here's Chunker error codes from three attempts I made

Hi, yes, please upload a copy of the world affected if possible. Also update us if the world could be updated successfully without corruption on the latest version.

Indeed, I had updated the world few updates ago and it works fine now. I have my backups on Google Drive and can provide links, but I would rather not share them publicly.
