I have two questions:
1) It's difficult to move underground (the path isn't always highlighted) why?
2) When completing the 3rd mission for Inferno, the number of heroes decreases on their own (e.g., there were 31 archers, and after two turns, there are 30 archers, and the same happens with all heroes). Is this a bug or a feature of the game?
2) I don't know, I don't think I've had that happen... Or maybe I just didn't notice...
