So much facepalming in my new fort, and it all has to do with the new military.
1) I embarked expecting to augment my food stores with hunting--and promptly discovered that crossbows basically don't work.
2) After playing with squad settings and getting familiar with them, decided to issue a kill order on a giant desert scorpion. A) The marksdwarf (who was cross-trained in hammers and therefore not completely useless) decided she was scared to leave the barracks, and kept running back every time she got more than ten squares away. B) My woodcutter/axedwarf, despite having successfully swapped between civilian and military status several times, decides that this time he needs to drop his axe before charging into battle. Hilarity ensued.
3) Marksdwarf gets over her phobia and catches the scorpion right at the edge of the map. She swings, she hits! --and the crossbow gets stuck in the wound. Oops.
4) One month later, I am informed that "Berlar, Giant Desert Scorpion has become attached to a pair of (pig tail trousers)!" Upon investigation I discover that yes, Berlar is wielding the unfortunate axedwarf's trousers and
5) beating the poor marksdwarf to a pulp with them. Literally. (Missing teeth, damaged organs, broken spine, massive bleeding...) Also, when the trousers get stuck in a wound, Berlar twists them.
6) Three months later, they're still at it. The poor marksdwarf is in even worse condition, but will not die. Or get hungry or thirsty, come to think of it. (I'm periodically taking screenshots of her [z] screen. The wounds section is running over 40 lines now.) I've had to disable the "Recover wounded" labor on all my dwarves due to job-cancellation spam.
7) In the middle of all of this, I noticed a new combat report. Apparently one of my war dogs killed a vulture, making it the best hunter AND fighter in my fort. And to think that I normally just tie them up to spot thieves...
