Have yoi ever gotten a propane tank from a barrel/crate and asked yoirself these questions?
WHY DA SHET THEY THERE?
THEY USLESS WHY THEY DONT REMOVE OT?
YOU CANT MAKE A GRILL WITH THIS, THEN WHATS THE POINT?
WHAT AM I GOING TO EAT FOR DINNER?
IS MY GENDER ASIAN?
Well fear not, this disscussion is for you!

Propane tanks were added becouse, they were... The creaators of this mod made them before thinking where to put the use of them. Since they didnt want their hard work to go to waste, they just simply added pronae tanks... As a loot drop that simply means that it was just a waste of your time to break that barrel.

How cuold we fix this? Well there are 3 ways for makers of this mod.
Easy: fk propane tanks and throw them out of the game
Medium: propane tank = 2 metal (needs heat +sum skill)
herd: Add a barricade that spreads the effect (recycle 1) then make the same thing as medium but with "recycle 1" instead of heat 1...

(Just take a look at the campfire and figure out how it spreads heat, then copy the stats, add them to an another barricade, but just change it to recycle 1) Its easy to say, but hard to make
