Question on BoP version 1.22.2-7.0.1.2312 With Forge 2582.
I am trying to remove the Flesh block from the nether. I tried to edit the visceral_heap.json file in the config, but this seems to be recreated each time I enter the world. I also tried to delete the file, but again it was recreated.
Where in the configs can I remove the visceral_heap biome from even being generated?

My test world is only Forge and BoP.

I should have looked through the closed issues before opening this. Changing the biome id to -1 was the trick. Nether looks much better now.
