Great videos (even though the fights are a bit slow a times, maybe up the animation speed? just a suggestion...)
I do wonder why you turned down the influence from the quest, even though you will need influence to use that wildland allies tech you are researching at that point and have no other influence sources in sight.
In episode 6, at time 15:56 there is one of those invisible rivers. Had that bug for ages, glad it also happens for other people, as I got no reactions to my bug reports about it. Look at the terrain indicator, it says 'river' even though the tile next to the river is highlighted. And the unit actually stops there like on a real river tile. So it is a real river tile, you just can't see it
