A couple days ago I played some multiplayer with my nephew. I made a fleet of small ships and gave them an attack order to the sector he was in. He was in a huge ship. He killed them all, I saw every single one of them overheat, as I was in my cloak ship watching. A couple days later, I was in single player, and realized the fleet was still listed under my fleet menu. I thought it was strange that they still existed. I gave the fleet a move order to my current position. I watched the map, and I saw the green ship icon moving across the galaxy map. When the ships arrived, they were all listed as overheating. And had overheating countdown timers. After arriving at my current position, they would not move, and stayed dead, like they should be. But when in an unloaded state, they followed my move orders.
