So I after my failed first attempt to start a space station around Duna (using the remote tech mod so I want a command station there) I decided to practice by putting it around the mun and sending the second piece that has a couple of landers to dock with it. After successfully completing that stage I decided to take one of my landers down to see if I could land and then redock to the station. And now comes the interesting bit (at least to me). I drove the rover around for a bit and upon attempting to dock it back to the lander it ended up stuck floating underneath, suspended by the magical docking force and the Muns gravity! (Of course I had also forgotten to turn off the tiny fuel tank I have on the rover thats sole purpose is to lift the rover up to dock and so the landers engines used up that fuel without me knowing. -.-')
