Worlds in 20w29a created in previous versions have different biomes on already generated terrain

In my case i created a world some time ago on one of the snapshots with new 1.16 biomes and now when i open the world in 20w29a, the place where the soul sand valley biome has generated, now is identified as nether wastes.

I tried creating a new world with the seed of this world (368836386368683368) and when i go to the coordinates where the soul sand valley has been generated, now there's a different biome - nether wastes. As if the game applies what biome is in what location based on the new world generation algorithm (if it has changed?).

I replicated it like this:

  1. Create a new world in 20w10a.

  2. Go to the Nether at 2, 95, 106 (or any other coordinates)

  3. Update the world to 20w29a

Indeed. Using early development versions like 20w10a can lead to corruption even in the long run.
