Looking for advice on building big ships. My issue is low frame rate, parts randomly exploding but most importantly.. attached parts start separating / levitating. I figured I should use less parts but I could only bring it down to about 500 parts. Additionally I now know to park large ships in different orbits (>2500m apart) but then o can’t take pictures like the one attached. When I send any of the ships out of Kerbin the frames improve but parts still starti behaving weird. My dreams of having a space fleet seem to be limited by the game, or my device. Thoughts?
