So I started playing DF again after a looooong while, missing many updates.
New fort, enjoying the new building features (auto vein mining is awesome!) when a werelizard appears outside. I hadn't finished setting up my military yet, but I send a lynch mob to punch the creature to death.
A few weeks in, one of my dwarves turns into a were lizard! He bites two more dwarves, who also turn into werelizards!
My fortress now has a full-fledged, uncontrolled lycantrophy oubreak - 1 in every 8 dwarves seem to be werelizards. I managed to isolate a few of them to a pit, and my marksdwarves seem to be able to take any stragglers down, but every time they turn they seem to be able to infect two or three more dwarves, and I can never catch all the victims.
I might as well give up and go full werelizard for this fortress

!!FUN!!
