I couldn't find any answer to the question asked hereinafter in the forum so far so I am opening a new thread as putting so much time in my GC this is of high importance for me.
I played all GC scenarios until East 43 and now instead of finishing the East 44 and 45 GCs decided to go for the GC West 42-43 since I wanted to avoid seeing Russian tanks all over for a couple of scenarios.

And I was right since this again is great work and brings some variety. But I have got a problem with my core status.
Before starting the first scenario St. Nazaire my huge and strong 41 army is ready to deploy and I have over 10k prestige. But after Nazaire all Units except the 9 or so I selcted for Nazaire are gone and even worse all the prestige. Now the Allies kick my a.. which is a nice challenge but I really would like to have some of my units dedicated for various operations such as Fighters and AT Units I did not bring to the first scenario of the GC West 42-43.
Finally my question: Is that a bug, did I something wrong or is it supposed to be like that?
Thanks for your help.
