Certain biomes, such as fen and bayou makes my screen really dark, and can only see light from celestial bodies and the horizon. I also have a few twilight biomes in overworld. Makes me think it might be caused either by changing sky colors in certain biomes or linked to twilight forest achievements. Any ideas how to fix this?
I think twilight biomes spawning in the overworld is caused by minecraft considering biomes with id above 128 as a sub biome, changing it to a number below 128 should work
