OK, so I've gotten the sulfur, salt, and coal. I'm all ready to combine them and blow some stuff up, but there's a problem: when I try to combine the coal and the barrel of salt, they both disappear without giving me a new mixture. I've tried combining them in my inventory and on the ground, and in both cases, both items simply vanish and leave nothing behind. It happens with combine lvl. 1 and 2- am I doing something wrong, do I need some other item, or is this a bug? Thanks.
