Hello!

I've been testing this mod in creative mode and I've noticed that the underground spider nest biome does not generate at all in the world no matter how high I set the spawn rate for it. Every other underground biome generates normally and I have been able to locate those other ones countless times but I have never found a spider nest, no matter how many worlds I generate or how far I explore.

While I did originally discover this issue while playing a custom modpack, I have found that this issue still occurs even with no other mods installed.

Here is my latest game log:

Here is my config if you need that as well:

If you need anything else from me just let me know.
