Being on fire increasing the temperature is hardly a crazy detail. Some would say it's the first thing you think of when you consider the status of being on fire.
This is totally possible, it's the flammable agent inside the bottle that is on fire, not the snow. Molotovs were used extensively in the winter war between Finland and the Soviet Union during WWII
Really? A k ? I had 3600 hours on my first play thru of Skyrim elder scrolls when it originally came out then my console got reset so I lost it all but a thousand hours with how long this game has been out ? That's short work that's a month at best and the game has been out for a while now
