Hey guys, I spent 8 hours building a very complex spaceplane that get's launched by two rockets taped to it's belly and back. After aligning everything properly I found out that I used the mk3 Fuselage with liquid fuel and oxidizer instead of the liquidfuel one. If I have to take her apart to replace this part I will lose many hours of tweaking and testing so it would be really great if you guys can explain how to properly swap out the parts trough savefile editing. A simple find&replace notepad job didn't do the trick.
