Hello, i dont seem to get the metallic hydrogen engines to work. Screenshot of my test stand is below. i have an IFS Cryogenic Tank with liquid hydrogen, a pressurized metallic hydrogen fuselage and the GX-820 engine + probe core, power and a few solar panels. In VAB and on the pad i see delta-V but the engine does nothing when activated and shows a third line "fuel amount ratio" with no value. First 2 Lines with Fuel Amount Ratio are both with 100%. Prop Requirement Met is 0% When i activate the engine and go to full throttle nothing happens. Then i looked into the mhEngine.cfgs an could not find what else is required. https://imgur.com/a/8IZtdyY Any ideas?
