In the advanced version of the rules for the Flash Point board game, there are Hot Spots which cause Flare-ups when targeted in the Advance Fire roll.
How are the players supposed to get rid of a hot spot? I haven't found a specific mention of it in the rules, so I just assumed it is removed when the fire and smoke in the given square are completely extinguished.
I have checked the official web, but the rule explanations there are only available for the Family/casual difficulty setting.
