So elf merchants arrive, and I trade them some rock craft for thier hippie goods, and a goblin ambush appears on my drawbridge, which gets ended with the only casulties being a few puppies. Then, as my dwarves are happily looting the bodies, I get the "Lora Eyamifava, elf Merchant has gone berzerk!" anouncement.
I gleefully watch my marksdwarves fill the elf full of bolts, as he tries to punch out his own mule. I then get the messages "Mule is stricken by melancholy!", and "Thalu Lalalaapasi, Elf Merchant has gone berzerk!"
My newly trained speardwarves put that mad tree hugger down just as quickly. (Interestingly, He died with a spear stuck through each hand and a bone bolt in his foot.) And then the "Mule has gone stark raving mad!"
Any thoughts as to what drove the elves crazy? My hunter happened to be killing game and fish all over the map while he chased a single marmot. Could it have been all the dead bodies of goblins and animals? Does this mean elf ambushes are in my future?
