Describe the bug

The nether generates with the overworld sky and biomes

How to reproduce

1. generate world, making sure that the spawn world is the overworld in the config
2. go to the nether

Expected behavior

The nether should have nether biomes and skybox

Screenshots

Can you provide a seed? Can't find that kind of biome in nether.
Yes, I also tried locatebiome

Seed was not specific, and I get it when generating multiple worlds.

Just to walk you through, I use GDLauncher and create a new instance with Forge 1.16.5 v36.1.31
I install SkyBlockBuilder 1.16.4-1.6.0 on that new instance
run once to generate config files and close
Set the Spawn dimension in common-config.jason5 to overworld
run the instance again
create a new world with world type "Skyblock", with game mode set to creative
in game I create a nether portal and go to the nether and can see that the biomes are not right

my guess is that it is somehow taking in the single biome feature you added in the nether world gen, even though the overworld is specified in the config, and putting the SingleBiome enabled value to false, seems to resolve this

Oh, single biome is true by default? That’s the real issue, thank you! I think I have to look at the whole default config.

Yeah, it is. Also, should single biome affect both the overworld and the nether even though only overworld is specified?

Oh true, that is an issue, too :D
