Posting from phone.
Ok so, meph is right. It was late at night, i wasnt really paying attention to what i was doing. Im not going to be back at my machine for a couple days and as such dont have much in the way of specifics.i didnt really mean this as a bug report, frankly im new enough to masterwork that its workings are still somewhat arcane to me, amd i figured this was yet another feature.
Furthermore, thanks for pointing it out. I wont forget next time as far as where to properly post. Since the thread is now here, ill post the details i have.
At any rate, this isnt race specific. I am playing dwarves. It happened to a goblin, a dwarf merchant, his yak, and a liaison all at the same time. The goblin was a snatcher. All units involved were startled on a one tile bridge amd dodged over the edge. They fell over ten z levels into a 2z deep major river, survived with minor injuries, amd were eaten by hippos something like 3 seasons later. The embark is a warm brdlf tropical forest with two waterfalls.
I am running win7 64x. The version will be whichever was available two weeks back. Ill even send you a dxdiag and/or the save if itll help.
