Throwing my hat in this ring. Iâll add the completely ridiculous bug of holding/carrying in some fashion a food/drink item and it freezes.
If at any time you hold a food/drink item and the temperature is THAT cold. Then your character is likely frozen dead. Sure some clown will bring up a few technical details of this. But in reality if you are holding stuff in your pack for example, and it freezes. Good chance you are dead.
Without getting overly technical about this. If you carry food/drink items. They should:
a) get warmer if frozen to a defrost point over a period of time
b)not freeze at all due to your body heat unless in the deepest levels of a frozen lab
c)should be able to eat and drink worn/carried items, but without a buff due to the discomfort of Cold
I mention worn because, Plastic Canteen, Hydration Pack, other canteen and garment containers.
