Fire Lasts Longer While Sleeping!

[Deathdealers747]

So, in Pleasant Valley on Stalker and Interloper Difficulties (and The Hunted, Part One), if you make a campfire and go to sleep, then the time left for the fire and the time slept don't match! The time left of Daylight/Darkness does match the time slept, though.

For example, if you put enough fuel on the fire to make it last 3 hour 30 minutes, then go to sleep for 3 hours, then you wake up and the fire still has 2 hours 15 minutes left on it - but the Daylight did, in fact, drop by 3 hours! I've noticed this does not do it when you make a fire in a Fire Barrel or a Stove, but only an Open-Campfire!

It has to do with outdoor vs indoor fires and it has something to do with the fire and air temperature on exactly how much bonus duration (or I should say, less duration consumed) you get. It doesn't have anything to do with sleeping; you will notice this bonus doing any activity. Generally fires at a 'stove location' don't get the bonus, but Fishing Hut stoves almost always do. Also, to further make it more confusing; making a campfire in the warm back part of a cave doesn't get this bonus, but a fire made in the cold outer part does. 

TLDR: This has been in the game for a long long long time (over a year now) and it seems like it is intended.
