If you weren't aware. Coal is very difficult to get on gleba only playthroughs. Burnt spoilage to carbon to coal synth is the only way to get coal. At default rates it takes 10 burnt spoilage biochambers and 2/3 of a belt of spoilage to make 30 coal per minute. Not even enough for 1 military science assembler. And you've doubled the cost of carbon from spoilage... Which means that it takes 15 biochambers running through almost 1.3 belts of spoilage for 1 military science assembler. I think I'm actually going to make a mod just to buff this one recipe
