-The Factory uses most of the body components now. The Extractors (there's four now, one for each spectra type) can consume meat, fat, spinal tissue, organs and horns/hooves. Bones are not useable, for now; probably won't be until the bug is gone.
-The extraction now produces a tool item and does not need jugs anymore. The items are processed at the rainbow smelter.
-Other parts that are usually just left in the refuse (cartilage, claws, teeth) can be put through a Grinder to make Rainbow Sludge, which has more some more uses.
Hey, that's pretty awesome. Less micromanagement for the damn jugs ;P
Just out of curiosity, though, will each pony body be able to produce much more spectra now? It sounds like that might be the case; unless you increase the amount of spectra needed to make rainbow bars it sounds like I can turn a stack of meat, organs and bones from a single dead pony into a ton of spectra (considering the sheer amount of organs any individual pony drops, it might be in the realm of one rainbow bar per pony, even).
For those of you who use raw ASCII graphics instead of tilests, you might be interested in a mod I made that changes the tiles of every sentient race to make them a bit more readable. It'll make every caste recognizable without the need to dig through descriptions and such;
you can find it at DFFD.
EDIT:
Ah, hell. Do you know about
the bug that stops creatures from growing after birth, Valikdu? I just now noticed that you haven't done anything to prevent it.
