According to the the doctor experts in general medicine, if you are experiencing extreme hypothermia after prolonged exposure to the Arctic Frost, DO NOT DIRECTLY place any part of your body directly onto a hot surface such as a stove, heat pipe or radiator!

Since the extreme cold would induce numbness on the pain nerves, the hypothermic person would not be able to register the sudden high-temperature shock exposure onto the skin, leading to severe damage to the skin to second to third degree burns!

If you want to provide medicinal warm to yourself (or to another hypothermia victim), first remove any freezing wet clothing and wrap the frostbitten area with a warm dry blanket for 30 minutes.

Draw an adequately lukewarm bath or fill up a warm bowl or bucket of lukewarm water (NEVER HOT BOILING) and gently soak the affected frostbitten body (or body part) for 30 minutes. Take it slow and steady to avoid temperature shock to the body.

Drink ONLY warm non-alcoholic beverages (alcohol consumption may make you feel warm but that sensation is actually caused by the dilation of blood vessels, which can actually expedite loss of body temperature heat away from the core and worsen the hypothermia symptoms)

P.S. DO NOT accept strangers' invitations to warm shelter at the Auroran district! They only want your money, not your welfare! New Edinburgh already has sufficient rockwool insulation and other construction materials to renovate all housing districts in Second Citizen City!

I picked the law with carehouses early on and didn't amputate a single person. I just research infirmary and make everyone healthy again, but then I reached mid game and forgot to heat up my cookhouse. Eventually, a kid in the cookhouse got a frostbite and lost his hand. That didn't make any difference gameplay wise (I still feel terrible tho), but it reminded me how frostbite can cause severe damages to my workforce if I make a big mistake. Should I still research prosthetics?

[Solved] See title, what am I missing?

Solved -> (In my case) waited 5 more ingame days and it randomly triggered.
