I had an odd experience I thought I'd share from a Dominion map.
At war across a river with another player, my fighter reveals 3 submarines. I attack them, because that's what you do with submarines.
Later, I realize I'm at war with the Ottoman Garrison, because the 3 submarines belong to them, not to the nation I was fighting.
Less concerned about my lack of attention that led to attacking neutral submarines, and more concerned about the fact that an AI with no harbours had 3 submarines in the first place.
Does Ottoman Garrison start the Dominion map with submarines? First heard, if so.
