I was doing a berlin 45 k4 campaign, in the 28th mission (another one of many where squad was moving to another airfield because of land invasion) after everytime I had to refly it, on pressing "quit mission" the pc speaker would beep, but nothing strange apart than that happened. Well, after completing the mission (another beep on quit), and pressing to see the next, another pc speaker beep followed and the mission debriefing screen is empty, giving me no mission to do.
After exiting the game, I opened dgenERROR.log and on it's line I can read "Cannot assign any town to Germany, 0 points".
So, I go back to game and load my campaign, the mission screen is empty.
So, is this the normal way for a campaign to end (including pc speaker beeps) when the war is lost? I'm pretty new to these dynamic campaigns altough I've had the game for very long, yet, I was having a ball!
