This mod disabled the spawning of machines faction from "man Versus Machine"

If machines from this mod are generated like biters then they will get disabled. Since I don't have good engine for adding additional spawners currently this might need to wait a while for a fix.

I looked at the mod code and it's unlikely I will make it compatible with RSO.
It would require work in both mods with some new external interfaces and additional upgrade to RSO enemy generation to cover more enemy factions and types of spawners. It's quite a big upgrade that I'm not willing to do right now.

alright, Thanks for looking into it.
