In my most recent game, my submarines are flagged as both INVIS and HIDDEN NAT. I, Catherine of Russia, was cruising a few subs past my locked ally Scandinavia (Marla map, accurate placement) en route to Cuba, and some viking frigates bombarded me. To be sure I didn't miss a frigate colliding with my sub, thus spotting it, I sent another over, and sure enough, it too was bombarded. How is Scandinavia seeing my invis subs? Does flagging Hidden Nationality somehow unflag Invisible To Other Units? A follow up question... I assume that cruise missiles launched from a Hidden Nationality vehicle would not be flagged as Hidden Nationality just because the vehicle was - even though the opposite would seem to make sense. Is this correct? I haven't discovered Rocketry in the game yet, and am curious. If I am wrong, then HN tactical nukes are going to make things interesting. Does the AI often make use of naval tactical missile carriers?
