Currently, I am attempting to edit a fairly large amount of mob spawns with Biometweaker and am also using the Tectonic datapack. However, Biometweaker seems largely unable to remove spawns from a handful of its biomes (but it can add them). In the logs, it seems to be outputting errors for these biomes along the lines of:

[21:37:28] [Render thread/ERROR]: No biome found for resource location tectonic:cold_river. Ensure it is correct and has there is a corresponding biome in the output folder.

However, all of the Tectonic biomes show up perfectly fine in the output folder.

Additionally, here is what my script looks like:

Tweaker.setScriptStage("FINISHED_LOAD")
