It's gotta be that early award date of the Tench, in spite of it having missions. I'll double-check the onboard equipment, but from what I remember, it is all active prior to the Tench going active...
I especially do not like it choosing a mission that is not assigned until after January 1st, 1945, although the mission files themselves are dated earlier. Why bother with dates if the game is going to ignore them?... Ahh well. We'll change a few things and see how it does after.
Let me search some more through your Save files the beast, and see if there's a way to change a couple of things... be back in a bit.
