One ship from fleet always trying to phase jump
I usually play as TEC (trying to learn one race at a time) and every time I move a fleet to a gravity well, one of the ships in the fleet (a frigate or a cruiser) will always turn around and go to the edge of the gravity well and stay there. When I mouse over that ship, it looks as it is trying to phase jump back to another planet.
The rest of the fleet goes off doing what it is supposed to do except that one ship.
Even if I give specific orders (move or attack), the fleet will complete the order and then the ship will go back to trying to phase jump by itself.
It is important to note that it never actually jumps, just sits at the edge of the gravity well.
Can someone tell me what is going on and why?
