What is there to disagree about? You've still got the same conning tower, correct? The way the game works beginning after the 4th patrol, is if you qualify score-wise, you get a new boat - if available. If a new boat isn't available, then you get a new conning tower, if available. If a conning tower isn't available, the game will ask next time you end a patrol. You haven't scored enough points to qualify, which is probably due in part to the way we changed the scoring, which is tougher now. The main thing to do is to complete assigned mission objectives, and you'll most likely need a minimum of two objective completions each patrol, together with ship sinkings. If you aren't assigned two or three objectives, you need to use the Status Update function to be assigned another objective after completing the first. You do still sink ships, but their importance in score tallying has been reduced, although they are still part of most objective assignments. Put that together with the fact that the Stock game had assignments out of Manila to start the game, that put the submarine in the Sulu Sea or other areas, where targets were few and far between early, and you might end up with a zero score to start your career, which is a deep hole to start in, math-wise, to try to raise your score from. I'll have to find that Ducimus thread again, which explains the base issue rather well - but you have to promise not to nod off to sleep if you try to read it...
