Made a peasant adventurer. Wandering around, some foocubi bandits were harassing the local market. Me and some random marksdorf I found decide to nut up and defend the merchants. The mace user drops without much trouble, but some incubus with a blade whip made a mess, tearing the dwarf to shreds and getting a chunk of my fledgling adventurer. (Red lower spine. Somehow not paralyzed?) A few rounds of combat later, the tide turns, and I hack into him enough to get him to yield...and promptly go berserk and start kicking at the nearest merchant again. So I continue my attacks, even messing his arm up enough to paralyze it and disarm him. Things seem to be going well...until I start getting messages about being on fire. After a missed kick from the mutilated horny devil. As inexperienced as I am, I didn't realize HOW I was on fire until I realized a few articles of clothing had combusted at some point.
Now in addition to my axe disappearing at some point and being on fire with no obvious way to extinguish myself, I also can't move for some reason outside of jumping. While the incubus was a non-threat at this point, my fate is sealed from the spontaneous combustion. And as an added bonus, I didn't think to save the text logs what might help you understand what happened.
What could have happened? I was just around a bunch of market stalls with food and clothing. Looking around didn't show anything obviously flammable. And why did the fire never spread past me? I know it's little to go on, but I'm super new to the game. I can probably be more helpful if I know what WOULD help.
