Hello.
1.4.5.2243
I was using quad nuke engines for large craft long range travel. previously all using liquid fuel as only fuel source, and suddenly before landing i activate new stage and my engine flames out? tanks full of liquid fuel i was puzzled, then i suddenly realised the engine required LH2 as a fuel source? what even is this?
I recently added new things to my tech tree to extend science collection but cannot see why that would mean all my nuke engines would need a different fuel source?
Can anyone suggest what to do? my ship is stuck dead in orbit with a tank of useless fuel.
Thank you kindly.
Nick
