Spawns vanilla biomes even if vanilla biome weight is set to 0 if there aren't enough TB biomes

[ShadowkillerGB]

What's the issue you encountered?

When there are too less biomes to load from (for example from BOP) TB spawns vanilla biomes even if vanilla biome weight is set to 0 in the config. This also seems to happen on older versions, not only 1.21.

How can the issue be reproduced?

• Install the newest version of Forge for 1.21
• Add TerraBlender and a mod that uses TB for biome generation (for example BOP)
• Set vanilla_overworld_region_weight to 0 in the TB config
• Disable a lot of the biomes in the biome mod's config

Additional information

I use this mod on 1.20.1. I know that you most likely will not fix this issue for older versions but if you would, it would make my life a lot easier

Seems like this isn't a bug of TerraBlender but rather BOP just replacing the disabled biome with the vanilla counterpart
