I beat on SK on easy today (yay!) and I encountered a few odd things along the way.

1. Some items had no image, their squares were just black. The same goes for a few skills that certain units and champions can use. I have the opt-in option, I don't know if has something to do with that.

2. The spell that allows the shadowlands to be conferted to normal works poorly. When cast you get 3 by 3 circles as a mouse cursor. When you have 9 tiles of shadowlands then you can cast the spell. However, when 1 square contains a tile of another sort (like dessert, forest, wasteland, etc.) or an object (like a tree, etc.), you get a warning that those squares can't be conferted. I would make more sense to allow the spell to take effect without affecting the none-shadowland tiles. Otherwise this spell is only usable once, maybe twice per game.  Same goes with that spell that creates fertile land.
