[MC-234014] 1.17.1 Spawn deletion

I had been playing on a world for ~4/5 months, and hadn't played for a week.

Loaded the world, and the world spawn chunks were reset to a different terrain/biome map.

deleted most of my work, and everything in that area.

Thanks for providing the requested information however, I can see that your game was modified when experiencing this issue, therefore, invalidating this ticket.

I understand that, but I doubt optifine would affect anything to do with this issue?

But, it was a clean Optifine mod, so I still reckon it could be counted as a bug, unless my laptop is broken. idk tho

Similar issue here. Upgraded to 1.17.1 from 1.17. World spawn shifted with spawn chunks. Now we're seeing generational issues where newly discovered junks don't connect/transition properly to the previous chunks (straight line transitions for the new chunk to the old).

Does this happen if you recreate the world using the exact same seed in an old vanilla version, then open that world in the latest vanilla version?
