For career mode why can't I port at any allied base? Do I have to refit at sub ports only? Because in the manual it states that I can refuel at any allied port, but I have to get ammo and torps at sub port. Can someone help me with this?

I would also like to port and promote my units but I can only port before starting a mission. So I can only upgrade my sub before starting a mission?

I am playing at hard difficulty and inputting data into the TDC and I cannot hit a target for the life of me unless its a shot under 1000 yards. Is this realistic? Is the impact and magnetic influence reversed? Plus it seems I always have to switch the speeds, depths, contact influence, and arrays for every torpedo.

Why can't I use my electric engines on the surface when I run out of gas? Because I can use them in conjunction with my diesel engines at surface. Am I missing something?

When is Ubi coming out with a 3rd patch? Boy I hope soon. I've been looking for answers for days.
