Frostbite code is a mess that is hard to review due to horrible practices, so it's no wonder that it not working went under the radar. It is also a mess when it comes to game design, so no wonder no one could (or wanted to) tell it isn't actually working.
Frostbite lacks a max_intensity field, meaning it is impossible to get frostbite, only frostnip
Risk zones are applied in inverted order - ascending. As a result, howling snowstorm will not apply frostbite (only frostnip) if air temperature is above freezing
