It's finally warm enough to start preparing the field. Kari tries to light and fire and gets a message that it succeeded, but there is no fire. Kari has successfully lit fires elsewhere before: in his fireplace, and on the ground near his house when he needed to light a torch in the middle of the night. None of my other characters are having trouble lighting fires, even ones with fields as large as this one. I tried closing and reopening the game, and leaving and re-entering the tile. I tried a few other bits of branches nearby, but haven't retried other worldmap tiles. Save available.

I left Kari's animals a few tiles away so the debug logs would be smaller and then tried to light a fire.
