If the campfire is extinguished manually (ie water, shovel, etc) if loses all of its contained fuel and resets to 0.

Could there be a way to have it setup that it keeps the fuel amount it has instead of resetting to 0?

Another suggestion is to possibly make it have a "Cost" to start the fire such as 10 seconds worth of fuel that way it makes you fuel conscious with the campfire.

Hmm, that's weird. I'll look into that.

As for ignition cost, it sounds pretty good. Thanks for the suggestion, I'll think about it!
