In my new fortress, I had a ridiculous chain of bad luck within about 10 minutes of each other.
It's 2 years in and the beginning of the third year in spring. My 33-dwarf fortress is doing fine, with making the barracks tower and the defensive moat/traps/defensive walls.
After a fey mood the year before which required absolutely no multitasking, the second one became possessed and clained a mason's workshop. First facepalm of the day came when I noticed that they say everything they need for their artifact in the Q menu. I only saw that he needed stone, so I used reveal (which is the only reason I had it on) to find what stone I didn't have.
All the stone I could see were mined somewhere else (not counting metal/ore/gems of course), but then I checked back and saw he needed cloth and gems.
Considering that every gem I could find with reveal was nowhere near anyplace already mined out and considering that he only got a stone and I have almost every cloth that I can import or know how to make, I simply labelled him as a lost cause and put my 3-man marksdwarf army to shoot him down when he'd go insane.
Somewhat later on, I decided to build a well. I already had the moat finished, so it was simple to channel some close to the main entrance. What I didn't consider, well...
Human caravans are at my trade depot, so I send my broker to go trade there. I check back to find out that he's not there. Guess where he is?
My trader is about to drown because of his own stupidity and I'm going to lose a legendary miner as well because of it.
And to add insult to injury, I wasted a lot of training time on my marksdwarves as the dwarf in a strange mood went stark raving mad, the harmless insanity.
Someone shoot me.
EDIT: I also can't get Dwarf Companion to work either... It would've helped me figure out what exactly he wanted.
