Absolutely not true. Prior to robotics (and now docking ports), there was nothing in KSP that altered the original part positions as defined in the initial craft created in the editor. The physical joints are created on a vessel load, using the initial parts position/rotation. When no robotics/new docking ports are involved, you can do as many save/load cycles as you want, the parts will always fall in place in the exact same position/orientation. The troubles started when, with robotic
