About a year ago, the great eye-lid-lacking serpent, Aste Odsenentol Dosta urer attacked my fort. Fortunately, my rag-tag military team was quickly able to stab poor aste in the brain with a barrage of not-so-finely-crafted copper spears. However, the tricky serpent had a few tricks up his sleeve, and several times before his death spewed out horrible vapors, leaving extract everywhere and leaving my poor military with a case of instantaneous full-necrosis. Only one of the original victims managed to survive, but died some time later, presumably tripping into a pool of extract. However, while the majority of the carnage seems to make sense, every month or so, I notice the dreaded purple clouds of miasma billowing out of my infirmary before another dwarf is rendered nothing more than a rotten pile of meat and bone. My question is, how come my dwarves keep dying? I've managed to clean what I believe to be every pool and puddle of extract, and I cant tell if theres any more via the stock menu. As a side note, it turned out that there was an explicit lack of shoes in my fortress, which I am currently addressing, but a military recruit was just taken down wearing what I believe to be only socks (do they help?). There seems to be no pattern, other than the fact that the majority of the dwarves seem to be from my military (even those who came recently). As another side note, the only time I've caught someone getting infected was when a hapless siege engineer attempted to do something to the last remaining exposed dwarf from the initial fight (presumable clean), and then walked away with a bar of soap before canceling his "clean himself" labor, falling unconscious, and rotting away. Is there Anything I can do to stop this? (Yet another side note, his blood still coats a section of my stairwell, but as I mentioned before, he had poisonous gas, not blood).
