I played a soviet campaign, level not normal but the one above against the AI.
Game version 1.02g
The campaign ended on a game over for me the september 31 1941. I thought the game was supposed to end in 1942. I do not understand why.
I'am holding north front very good. There is a huge battle around moscow and i'am holding.
South front is a disaster i just lost stalingrad but it is not in the soviet sudden death condition in the manual.
The manual say sudden death only if i loose my 3 big cities. And i still have leningrad and moscow.
Any one know why my game ended ? (And it is only a minor german victory, so even the german AI shall be angry of the stop).
My final position screen :

Great job whatsoever the challenge offered by the AI is interesting !!
