Hello.
I've seen this a few times. I say, 'Save and Quit' from some place, where it comes up, after a successful expedition.
When I turn the game back on, it shows the data from that save (2/6 200 fame for example) but nothing happens when I click it.
I can start a new game, and I have unlocked some characters to play in a new game.
Is this a game where you must play the whole campaign (6 expeditions) in one sitting, or a bug?

edit to be clear: The game has never successfully loaded a saved campaign. Alpha 28 A Wonderful World. I've had the game for 2 days, no version change since I would have to download it from GOG
