Odd OBB/ campaign buy screen problem ...

[Arralen]

I'm having a very odd OOB/ campaign buy screen problem, and at first I thought I caused it myself by fiddling with some unit structure etc., but I went back to the default OOBs, and things do not look much better then.

Long Campaign, Germany (OOB 16).

Start date: 2/40 - 5/41
In every case, the "Armour" buy list does not show it 2nd page.

Only from 6/41, with the east front opening up, the buy list becomes 2 pages long.

I suspect, though, that this is in error, and that there are a handful of formations which should be available, but cannot be bought, because the list does not roll over: When buying for a single battle with the same date, one gets nearly 2 pages full of formations ... .

This problem became apparent to me when I, as I said, fiddled with F349 (3 gun platoons, 1 scout group + car as command squad - why aren't there any command squads, btw.?).
Changing the formation made it drop down to the end of the list - where it was visible in single battle mode, or from 6/41 onwards in the campaign (though it's available from 2/40). From 2/40 to 5/41, only the squads (F348) where visible on their "old place" in the buy list!

EDIT: Here's a screenshot - default OOBs to the left, my OOB to the right. Both buy list @ 5/40, Tobruk. As one can see, with the modified list the "PzJg Kp Sfl" has vanished from the list (dropped down to last place, on the unaccessible 2nd page), and the "NbFz Zug" has appeared instead.
