I have a similar problem. My small fleet ran out of fuel in high orbit. I sent a small shipment of fuel and then sent the fleet on a further voyage (without the small transport ship). I gave the order to the little one to return to the colony, after which I got a report that 1 vespene was missing. Now my little freighter has been "hanging" near the planet for two days. I can't find a way to bring him back to the colony. No important cost, but I lose the ability to send another fleet. What should I do? There is a self-destruct option? :) Regards
