After slaughtering a bunch of goblin invaders, the dwarfs promptly piled up their corpses in my refuse pile.
Fast-forward a few seasons and the corpses decomposed to the point where only their skeletons remain. Being low on ammunition at the moment I decided to put those goblin bones to good use and make bone bolts out of them, like I sometimes do with cows and kittens.
Trouble is, the dwarfs refuse to make bolts because they need "unrotten bone body parts". But I have more than two dozen skeletons outside!
Can I use those bones or not? If that is possible, how can I get the dwarfs to make nice goblin bone bolts, so they can take out the next wave of besiegers with the goblin's own ancestors?
