I had a flyer on Sanctuary moon and made a blueprint from it yesterday. Today, I flew it to Sanctuary 1, and took the shuttle to Alioth. I took a complete set of equipment to duplicate the flyer, which I did once on Alioth. Later when I checked my map, I saw the original flyer was no longer on my construct list, and it was no longer at Sanctuary 1 on the moon when I returned. It was a long trip back to my home by jetpack. I only left my original flyer at Sanctuary 1 for about 5 hours. I suspect this is a bug, or else I do not understand how a blueprint is suppose to work.
