Cobblestone is flammable, but crafted with only Cut Stone+Flint?

All turf is flammable with a torch. The only turf that won't smolder (but can be burnt with a torch) is scaled flooring.

It's intentional, as well as with every other "stony" turf, like rocky turf, cave rock turf, checkered flooring, etc.. Where else is all the turf gonna go if you have too much and can't burn it?

Thanks, I was thinking it was an overlooked function from when Cobblestone required Boards to craft, if I remember correctly. I didn't realize every Turf was always flammable. Sorry to draw attention to something that isn't a bug.
