Title, basically. I was excited to have two separate production lines barfing out rocket fuel but the methane-based one can't be crafted in chemical plants, assemblers, or by hand. Here's a little screenshot to show: https://imgur.com/a/10fE6ZX

Oh, sorry, I fixed this in the latest release, but I haven't updated yet. Will update soon so this can be made in the chem plant. The problem was that it was set to crafting-with-fluid, to be made in an assembling machine, but the vanilla assembling machine only has 1 fluid input, while the recipe needs 2. Took me a while to notice because I add more fluid inputs to the type-3 assembler in another mod. Thanks for letting me know.

Should be all set. Let me know if you have any other trouble.

Works great, now I'm drowning in rocket fuel.

Is it too cheap? I thought adding the steel plate gave a bit more balance. And 200 methane is, uhh, only 10 solid fuel, but that's with the coal required as well. Should I raise it to 500 methane? Right now the balance is just based on a somewhat realistic view of the new, real-world process of making rocket fuel from methane (thank SpaceX and a few others for that one).

I think it's fine, I was commenting on the fact that I made waaaaayyy too many assemblers/chemical plants for manufacturing it using both the vanilla recipe and this one separately.

If anything in my specific case the steel presented a good (though inconvenient) hurdle to overcome since I'm doing all of the primary oil products that don't need other resources in a separate base and as a result I didn't have spare iron/steel/whatever laying around to belt over.
