I've recently had 2 dwarves get a single mangled injury each because of a stupid merchant bodyguard that led a bunch of unicorns smack into the middle of my fortress (2 other dwarves died). Now, instead of going to bed and resting, they run around, trying to drink/eat/do-anything but keep falling unconsious before they can get a single thing done. They're basicly flapping around like fish without water and refuse to go to bed like normal patients (although that would result in tantrums and berzerkering, no doubt). One's got a lower body injury, the other's got a head injury.
While we're at injuries, the health care in DF is terrible.
My last injured dwarf was left to herself in a room and no one even bothered to bring her water in a bucket. Of course, she eventually went berzerker.
I've yet to have healed a dwarf with yellow/red injuries, nothing pleases them. I throw in a chair and half a second later of being content, the dwarf throws tantrums again.
As much as this game kicks ass, it really needs medicine, euthanasia, or both.
Was even thinking of making an euthanasia room, which would flood dying dwarves and send them into the river. Cruel, but so is dying of hunger and thirst. :S
