Upgrading the unterseeboot

[9emini]

Ahoy mateys!

After 7 (SEVEN!!!) time compression-less patrols in my trusty IIa (a career I began in December, for obvious reasons) I've earned enough renown to upgrade to a VIIb. Woo-****ing-hoo!!! (That's 71kt of allied wreckage, not to put too fine a point on it ;-) ). I'm not sure if the behaviour of the game after the upgrade is 'normal' though: I'm warned to visit the barracks after upgrading as I don't have enough sailors. Fair enough - to the barracks we go. When I get there I find that I've got two more sailors and two more petty officers already on board - with the latter both being qualified torpedomen. Is this usual?

The second problem I have is that despite only engaging (and subsequently sinking) two craft during my last patrol, and those two craft clearly being listed as allied craft by the game before I docked at Kiel, a save named "The war ended!" is created as soon as I dock. I can leave Kiel in my new VIIb just fine and even save a new game after leaving just fine, but if I go to load such a save the "war ended" save is the last save listed.

Now, it may be relevant to point out that as a result of this latest patrol SH3 tells me the following (on the 'patrol history' screen):

You've been awarded
Iron Cross, First Class
German Cross
You've been promoted Oberleutnant z. S.
Your crew earned Promotions

Prior to docking I was merely "Leutnant z. S."

I hope I haven't been promoted out of my career altogether! I've had a quick look in the careers(_0).cfg files and apparently warended=false, so am quite baffled by this . Appreciate any thoughts the good folk here can offer!

Using GWX3.0.

edit: actually, I lie. Before I dock, Finished=false and WarOver=false. After I dock, both become true. So I can just dock, quit game, edit careers.cfg appropriately, restart game, and all will be well? I hope so! Any idea what leads to this behaviour in the first place?
