Fire needs to be able to be put out, if it can be put out in real life, then surely it's able to be put out in a game with near perfect physics. I find myself trying anything to put out fire, but to no avail, nothing seems to work. Making it cold doesn't seem to put it out, "suffocating" it with a material doesn't work either, and neither does pouring water on it. Which leads me to believe that there is no way to put out fire (other than to erase it or the material it is burning) implemented in the game. So, I think there should be a way to put it out.
All flammable materials weren't able to be put out last time I tried it. But all of the sudden, no matter how big the fire, I'm able to put it out, now. I guess I found some sort of gltich?
