After attacking and killing the first ship in an enemy stack, the second and subsequent ships in the stack can become invisible:
The highlighted tile immediately to the left of my fleet contains the invisible scout ship, plus a bunch of others under it.
Have encountered this too every fight until my latest game when some Iridium ships did not go invisible at any stage of attacking their stack of three or so ships - so what I thought was a straight bug has now become intermittent it would seem.
At a later point, my own fleet became invisible. In case it's relevant, in both cases the invisible ships were in a tile immediately above and to the left (northwest) of a planet.
I've also encountered this against the Drengi.
They create large stacks of ships, after the first combat the stack seemingly disappears but it is still there. Seems like a mix of fleets and individual ships in the hex.
Once you get through some rounds of combat and whittle down the stack, usually a ship will reappear.

I found that same thing when colonizing a planet and a ship was a near it. Clicking on the hex would make the ship appear.
I've this issue too, I attack and the enemy ship disapear, if I unselect my fleet after the attack the enemy ships appear, but if I attack again the enemy ship disapear again.
I add this too. I finally figured out about the invisible ship after 3 turn of <Why the hell sentry mode is bugged NOW?>
I tried moving my fleet around the planet I was "blockading" suddenly killing those invisible bastard!
