Fire Mages ignite shouldn't set critters on fire if they won't die from the damage.

Fire Mages have a passive ability that spreads a dot around nearby targets.It lights critters on fire, but they don't take damage from it and I have no idea why.They run away from me, I can't see them because their health bar doesn't show up at all, and I am locked in combat for like 30 seconds until I move far away enough or I find them.This is really annoying and such a weird oversight.Edit: I think the simplest solution to fix this would be that combat with critters doesn't actually put you "in combat".
