It's Groundhog Day in the fort whose name I never even thought to look at. A kobold thief got caught in the soil level, and decided to run straight through the locked door into my magma pump stack. Which wouldn't have bothered me, except that he then changed his mind and ran back, trailing flames, straight into the thick cave moss floor. Which is where my entire food industry, livestock and all, resides. Just before the first booze pot started to boil, the seasonal save hit.
Problem is, as soon as the whole room burns down and the last flame goes out, Dwarf Fortress crashes.
Watching the busy soil layer burn is kind of fascinating. I've done it several times now. There are ways out on three sides, and it turns out that livestock are pretty good at finding places to run--way better than dwarves chased by enemies, that's for sure. There's also an animal stockpile with a number of goblins and two minotaurs there; inevitably, one minotaur survives the wall of fire and escapes its cage, then is shot to death by an archer. I have no idea why the archer is there, besides that he can ignore the "stay on stone" burrow I set up. I'll have to check his preferences and see if it says "likes schorl, mittens, and smoke inhalation."
I guess I'll try using DFHack Liquids to douse the flames, to see if I can get past the crash. I'd hate to lose the fort to a bug.
