ok now I feel truly silly, because this mod combined with natural evolution enemies will over time cause slowdowns and massive lag
the reason I think is because natural evolution enemies causes enemy's to drop 'small alien artifacts' when they die and by the time I started to get strange slowdowns I had some 130k of them on the ground, somewhere
so if your going to use the two mods together I advice having some way to clean up the 'artifacts'. ether some type of mod or just going out to get them
