I think the developers overlooked a lot of things. In my third mission, Wier was actually an enemy, but some people say he's somewhere in the water... After I killed him, he calmly participated in dialogues as an ally... And if we remember the disappearing fortress in one of the previous campaigns, for the Haven faction... As for accumulating 1000 points for demons, it turned out to be not that difficult, it's tedious and takes a long time, yes, but it's a long time in real time, not in-game time. You divide imps or succubi into 3-4 stacks and go for it.
