In the new terrain generation, seems like shattered savannas got very downgraded compared to how they generated on previous versions, often generating in very small sizes on coasts and surrounded by water. 'Downgraded' might be interpreted as an opinion though.

I also noticed, that most of the biome terrain is "stolen" by other biomes around due to the new biome placement. That's why they now lack a lot of the shattered terrain they had before, often appearing "over-shattered". Most of the terrain on the surface is just water.

Expected result

The expected would be, to not find almost every single shattered savanna with low size and lacking terrain (most of time due to water), like how they were to generate on 1.17.

How to reproduce

Due to the nature of how biomes / terrain generate now, you may have to check a lot of times. Seed of the attachments: -8330603083619589917

1. Create a world.
2. Locate a number of shattered savanna biomes.
3. You might see how almost every if not all of these biomes are very small and surrounded by water.
