So. I spent hours on a build with the new ion/nuclear engines mod (new to me; I've been a vanilla player until this week.)
I built a great interstellar probe. Heavy as hell, so I figured I'd save the chassis and build a manned version. (Sub-assembly)
The first time it worked like a charm and I made interstellar orbit. But: I forgot to replace my solar panels
So: I revert, add the forgotten reflecty material, and get back to the launchpad only to find that my throttle is stuck at zero.
I'm talking Mjolner status refuses to move. Now: if I stage through it? The upper stages...as they're exploding...show full thrust and the throttle moves. So I figured it was a glitch in the sub assembly.
I recreated a sub assembly from my working probe chassis, and same result.
Please advise. I don't want to spend hours recreating this build only to find the same result.
