If thats any of help for others in the future, when I place player subs within visusal range to enemy, miraculously the the game doesn't end. Subs placed futher than that - game ends after 30seconds. Means no "patrol" MP missions, nor searching sector for targets. ...unless the trick would work with placing some stationary enemy merchant near the player start location, and go from there. Not sure if it would work though, and what will happen when you leave the merchant away from visual range. I used so many bad words trying to sort that out, but had a successful MP mission done today with 2 Uboats - yppiiee!
