The Front Desk Lost My Tonnage!

Greetings All!

Running latest patch to SH III with Real U-Boat 1.45 and SH3 Commander installed over all of that. Since Kiel is out of reach many times due to fuel considerations after my patrol, it's not uncommon for me to swing into Wilhelmshaven to top off, re-arm, etc. then go scout about a while then head back to my home port of Kiel. However, this last cruise costs me some tonnage on a medium freighter I sunk. Upon returning to Kiel I noticed my log didn't register the ship (after opening SH III the next day to continue my cruise).

Soooooo...to be absolutely sure all tonnage, etc. is saved after I pull into ANY port, what's the recommended proceedure? I always pull up to the dock, hit "Exit Patrol" then in the lower right "Dock at blah blah blah". Then exit SH III completely if done OR if I'm going to keep playing stay within SH III nav to the Career On-Base screen, hit the "Mission" map again and go back out. I guess the problem is occurring when I exit SH III completely. Should I hit "Save" instead? Do what I am doing but hit "Save" and back out completely and re-open with SH3 Commander each time? I dunno.

Sorry I'm so ignorant. In real life I'm a janitor.

Sincerely,
Jeff
