In my current game, the mobs from this mod are appearing in normal, nightly mob/Monster spawns outside of the structures from this mod.

Not sure if this is intended. I assumed the creatures are unique to the graveyard structures.

It is intentional. They can be disabled in the config though.

I looked over the Config. No Way to constrain them to this mods placed structures?

Thanks for the replies.

If you disable them, you disable them from spawning naturally, not from spawning in structures.
And by looking at the picture it looks like a horde spawn. That is still possible even when you disabled the natural spawning - so you would need to disable that in the config too!

I Don't Mind the horde. The ones just in the field like other monster spawns at night, that's what I was after! Its nice I can disable them, I want them to be semi rare.

Prefect.
