I was attacking an asteroid and after all enemies were dead, half my fleet decided to fly vertically upwards and half vertically downwards. Now from the zoomed out view it looked tlike they were parked there, but when I told them to move I was a bit worried when 1 hour later they were still not jumping. hmmmm...my fighters and bomber were waaay down and the rest were heading upwards. had to order them to attack the asteroid (again) wait for them to get back, and then tell them to jump.
