You rarely see anyone fly any of these ships anyways.
To try and hit it, envision the ship, and use the crosshair to help you see where the ship is going, should be easier to hit it. Hope that helps you snipe them until the update comes and fixes them.

Or do you mean why they got invisible after their up-scale? I dont know that myself. Maybe it has something to do with the hitbox and the Model of the ship. Dunno
