So look at this nasty bug I found the other day: I had run out of fuel when I absent mindedly agreed to give 3 of my 4 fuel to a person in need, only noticing afterward that I was so low. So you drift in space waiting for events to happen, which got me scrap, drone parts and other things that weren't fuel. however, once I was overtaken, I was pretty much hosed so I clicked on hangar and started a new game as an engi ship. But low and behold the game still thought the fleet was where i started. Yeah. needed to restart.
