I keep having a strange bug when I start a fort. It only occurs occasionally, but one dwarf will spawn wearing either liquid fire gloves or socks, and the map will be consumed by a fireball, burning the entire surface to ash. This is more of an annoyance than anything, as everything is recouped quickly enough, but it is rather irritating to lose half a fort's population along with every animal because someone wove their socks from liquid fire for some reason.
I'd really appreciate anyone able to explain what's going on, even if there's nothing to be done about it, because I find it rather peculiar.
