Adding mobs to nether with config does not work

[NixityNull]

Adding "nether' or nether biome ids doesn't work. I suspect that it is because the nether is turned off for all the mobs spawning but is only configurable for the lost miner.

[Xratedjunior]

Nether is not turned off for the mobs, but all the mobs have certain criteria for spawning. I think that's obstructing the mobs from spawning. However, I will check it.

I am trying to put the jungle creeper in a modded nether biome from biomes o' plenty. Do you know what might be causing it not to spawn? Here's my config for reference:

[Xratedjunior]

The Jungle Creeper only spawns on Grass Blocks. I don't think that Biome has that in the Nether so that will probably be why they are not spawning.

Is there any chance you could add a spawn block config?

[Xratedjunior]

Yeah I'll try to think of a solution.

[Xratedjunior]

Fixed in later versions of the mod. (Changed Mob spawn criteria)
