My L ship is leaving travel mode for no reason and losing shields, I'm in empty space, there are no asteroids or lockboxes the ship can hit, but it still keeps disengaging travel mode as if it crashed against something losing half the shield in the process, it is a pain to traverse even one sector. It also disengages travel mode when I enter the map, I have the option turned on in settings and with smaller ships it works, not with my destroyer.
