So, i've seen a bit of an uptick in NCLS with cotton root bark applied since there is the new "Claim 50 NCL's" quest.
My theory: if you get a gal pregnant and then chase her, it's the same effect as CRB: she looses the cubs, and thus, will have a greater chance of producing a mutie.
I've been impregnating as many lionesses as you can before chasing them. Anyone else doing this?
