Do you need 1 captain for eatch ship?
I was under the illusion that you could use one captain on a ship that he earlier was trained for...
I just got the Nagato, but didnt sell the Fuso. I trained the FusoCaptain into the Nagato. Afther playing a couple of games with my Nagato i wanted to have a couple of matches in my trusty old Fuso, and i though i could just assign my Old captain back to the Fuso, but it seems like i have to retrain him again
