I am on my third rocket, and have had trouble getting all three to load fuel. The loader has power, has fuel, rocket is on the pad, but the loader is not loading into the rocket after pressing "Load Fuel." I have tried replacing the launch pads, the loader, filling the loader all the way full, none of which help. I read one post that said it only loads from the right side, and have changed the position of the loader to other places, still no luck. What's the work-around, if any? Thanks.
