The mod is great so far, but I'm running into 2 problems: #1: I'm having trouble figuring out the QVP mode on plasma thrusters. They're supposed to work in a vacuum and require only megajoules, correct? It seems that no matter what altitude of the ship (90km or 900km), the QVP doesn't kick in, even when selecting "Auto QVP." All that button does for me is switch to liquid fuel. I'm not sure how high you need to be, but I imagined that 900km would be high enough for a vacuum. #2: Parts don't tweak. I don't see any kind of tweak scale slider on any of the KSPI parts. I went ahead and installed the full version of tweakscale, and went through the troubleshooting section of the mod, and still nothing. I imagine this is a problem with tweakscale rather than KSPI, though. I just imagined that a bundled version of tweakscale would work "out of the box," but I must be doing something wrong. It was a totally clean install for KSPI and tweakscale. Anyone have any ideas? Yes, tweakscale is in the gamedata folder.
