On a related topic, the MFR Leaves can't be composted, either. Just to save you the iron (or invar) and inventory space.
Most of my derps have been the classical sort -- is the mob grinder filling? How quickly can I get rid of this spare scaffold? What's that hissing sound? -- but then there's lava. I have what you might call an unhealthy relationship with lava : I use it for everything, and it gets drunk and lights my stuff on fire. Like when I tried setting up a magma crucible array on my farm platform. My wooden-platform-and-tree-filled farm platform. Well, used to be wooden-platform-and-tree-filled.
Might have the alcohol in the wrong place.
I've got a cobblestone foundry island, where some of the heavier industry and such goes on. On the top floor, temporarily until I have a power island, is now the magma crucible array. I'll eventually have it piping to the engines and tanks and such, but I'm still early enough in game that I don't the resources for that sort of automation. But I do have the a Tinker's Construct smelter for ore doubling. When the smelter's low on lava, I can just grab a bucket and refill the tanks, easy as can be.
And a careless right-click is how I lost my Frying Pan of Destiny, as well as a life.
