After attempting to attack a spoiler race, I lost all fighters from a carrier. From that point on, my carrier could not move.
I tried deleting all empty squadrons, multiple types of move orders, dividing the ship out of the fleet, SM teleport to Earth, and reloading the game. Nothing will get my ship moving again. It claims to have it's full movement speed, but never goes anywhere.
In the included DB file, the ship in question is the CV-01 SFS Warrior (in a fleet of the same name) now orbiting Earth. It is attempting to refuel and will never succeed.
SJW: There is no DB in the included file - file size is 0.06 KB.
