I'm playing a game with some random Harder AI types  and one of the types has Planetary Cloakers on all (or at least most) of their planets Which is cool! Except that if I use the galaxy screen then use the "Displaying" setting to check for things like Fabricators  ARS  Backups and so on  it will still tell me what is on the planet  even if I haven't blown up the Cloaker
