I'm trying to complete a career mode contract that requires you have 4000 units of liquid fuel in a space station. It seems this is impossible because with the RO mod, it removes liquid fuel with the RF config that is with it. It's not recognizing kerosene as a replacement, and RO doesn't work with RF stockalike. Any way to add liquid fuel manually, or tweak the contract to use kerosene or something else?
Edit: Ok nevermind, looks like I was able to unlock the non-RO engines later, which unlocked (I think) Liquid Fuel/Oxidizer (stock), and it only works with the stock fuel tanks, not procedural tanks.
