I need to get coprite for my base's farm. All the farm specialist is telling me that it comes from "overfeeding" creatures.
However, I can't seem to overfeed them - I feed them once, and they smile and cavort, but then I can't feed them again. I've hung around a while, but no coprite seems to appear.
Is this just a case of "wait longer" - is it a random thing (in which case, should I just feed as many animals in the herd as possible?). Or is it specific animals (so far, I've only been feeding small herbivores)?
