I'm trying to build a station. I'm using Mechjeb to do the initial docking (since I suck at it and couldn't care less about doing it manually), however the parts are usually rotated wrong. So I'm trying to undock, rotate the part so that it looks nice, and then move back to dock again. But it doesn't work, when I try to dock it just bounces off. I'm less than a meter away from the docking port at most, and the docking port is lined up 99.9% (I checked). What am I doing wrong?
