Yeah, we have a bunch of threads discussing this, but I just thought I'll give it a proper write-up for the devs' sake:

 

If Black Magga eat the last card in HCtF and the players have won: the players will receive Gold and reward (the collected allies), and on the Scenario Selection screen, this scenario/difficulty will be noted as 'completed'.

 

However, the next scenario or a higher difficulty will not be unlocked.

 

Also, when the above bug occurs, the ending cutscene will display black background, instead of the red 'closed location' artwork.

It's slightly different but:

 

The same thing happens if the party has won and time runs out.

Do you mean when you use the 'Forfeit' button? Because that makes sense in conjunction with the original bug, as the Magga is eating all the cards, while you're spending empty turns.

In theory, yes, but in practice, I don't think Magga eats if you forfeit.  Nothing seems to indicate that she's actually consuming cards when the game burns the deck.  However, I honestly think that any scenario you forfeit should be unwinnable by default.  This is the only scenario I know of where "time out" doesn't automatically fail.

I can confirm. I accidentally did the scenario on medium instead of easy so I forfeited at the start and got the victory + gold (but didn't unlock legendary.)
