So I started a fort and everything was fine. Workshops were being set up nicely and life was good. Then one of the fisherdwarfs went into a fey mood and claimed a craftsdwarf workshop. He proceeded to get two logs and subsequently screamed for a tanned hide. Not wanting to slaughter one of my wardogs, I sent out a military dwarf to go a kill a deer, so I could use its hide for the dwarf in the fey mood.
I assigned an iron crossbow for him to use, overlooking the fact I didn't have any bolts. He ran off with the crossbow and attacked the deer, bashing it with the crossbow. The deer got bruised, tried to run away, repeat. The dwarf chased the deer around for 10+ minutes. Me, wondering why it took so long, realized there were no bolts and the blunt damage wasn't actually doing much. The only thing that happened was that the deer lost a hoof and got a bit bruised.
So I decided to make the military dwarf a sword to use, assigned it to him and de-assigned the crossbow. The military dwarf picked up the sword just fine, but didn't drop the crossbow, no matter what I tried. I forbid the item, told him to dump it, but nothing. So I hoped the guy would wise up and actually use the sword instead of the bow and I sent him out again.
The deer was still on the map and the dwarf started to chase it again. After a bit of a chase (I didn't know deer with only three hooves could run so fast...), the dwarf started to attack the deer again, with his crossbow, while holding the sword in his other hand. This proceeded for another 10+ minutes, in which the deer lost an ear and its three other hooves.
After this, the deer was still running, being beaten unconscious every now and then, only to get up and run away again. At this point I threw my hands up and gave up as my military dwarf was starting to starve. So the dwarf went home and I closed off the workshop, waiting for the fey dwarf to go insane or my military dwarf to be done eating, whichever would happen first.
The military dwarf was done eating first, but by that time the deer had somehow found its way off of my map without dying (even though it had no hooves and was bleeding) and a few seconds later the fey dwarf went insane.
The military dwarf did not let go of his crossbow, nor of his sword. The insane dwarf was caught in a cage. The deer survived.
All thanks to blunt damage being quite useless, and the retarded dwarf who would not use the sword over the crossbow even though he had no bolts for it. Gotta love that.
Oh, and poor deer. I really feel for it, that it had to survive all that.
