I just started a new game to have the new update stuff. After scouting the world a bit I embarked in a temperate
I had just dug a entry tunnel and built a bridge over a river to set up base in a easily defensible position. Suddenly, two dwarves cancelled their wood hauling jobs as one started attacking the other. It is approximately 22 Granite 125 (less than 10 days after embark) and there's already a temporary meeting hall in the entry tunnel, next to a frozen waterfall. They were outside crossing the bridge. I was not able to see which way they were going.
Dwarf #1 (the Carpenter) was enraged at all enemies. She is apparently "assertive to the point of aggression, unwilling to let others get a word in edgewise when she has something to say. She is given to rough-and-tumble brawling, even to the point of starting fights for no reason". Dwarf #2 (the Doctor) was attacked, and now has structural damage to the upper and lower body, both legs, left arm (lower, minor injury in upper), left foot, and guts; function loss in right lung; and broken left hip. Carpenter has structural damage to upper and lower body, head, neck, left arm, right hand, left leg, right foot, liver, and left hip; and loss of function of pancreas and right kidney.
Dwarf 1 is now back to normal and satisfied upon improving fighting.
Why does this happen and what can I do to prevent this from happening?
(At least it was the woodworker, not the miners or woodcutter)
