TerraBlender 1.19.2-2.0.1.127 breaks Fabric Biome API biomes (including Cinderscapes). Traverse and Terrestria depend on TerraBlender, so effectively this means in 1.19.2 you cannot use Traverse or Terrestria with Cinderscapes and actually get Cinderscapes generation. Cinderscapes biomes exist but cannot be found via the /locate command and if you find them on foot they are missing all generated features. I have raised this issue with the TerraBlender folks.

Here is a comparison to give an idea what this looks like in game (proper gen on top; broken gen on bottom).

I've submitted a fix for this bug to the TerraBlender authors so hopefully there will be a new release of TerraBlender resolving the problem soon. I'll follow up with updated versions of our mods requiring the new TerraBlender version.

The new TerraBlender release -- 1.19.2-2.0.1.128 -- looks good. If you need to run older versions of Traverse and Terrestria alongside Cinderscapes, you can hot patch this issue by also including the new TerraBlender version.

The new build is up on Modrinth and eventually CurseForge.
