I am in the middle of chapter 4 with 58 of 75 provinces explored and my scouting difficulty is "hard". I know Inno has made the early chapters more difficult but this is ridiculous. I just completed a squad size increase and my difficulty went down to medium for a day and a half then went back to hard. It increased for no reason other than time period. What gives? Is this a bug? At any rate the chapter is going to take a very long time to complete unless the exploration difficulty changes. If I weren't an experienced player, I would have quite awhile ago. There is such a thing as too hard to be enjoyable!
