Bugs (you may already know them, but just in case)
1) When the select a new spell screen popped up, 2 spells showed zero turns to learn. I selected one of these and I instantly learned it, bringing me right back to the choose a new spell screen. Repeated on the second “zero to learn “ spell. This time the choose a new spell screen did not come up. After that, I could no longer learn new spells. The small green circle that shows turns remaining to learn current spell (bottom right of Manage Magic icon) would display ~”currently not researching a spell” (sorry, do not recall exact wording). Clicking on it would only bring up my existing spell book and I hand no way to select/research a new spell for the rest of the game.
2) Had a city with the warriors aura spell (+2 level bonus). Units trained or summoned in this city did not receive the +2 level bonus.
3) SK’s garrison’s on map could not be moved onto. I could march up to it and fight the SK’s army standing on the garrison but then could not move onto the square to collect loot and no new SK units would spawn there. I have only seen this happen twice.
4) When an allied army parks itself on one of your outposts, there is no way a pioneer can move in to upgrade it. Game thinks you want to talk with the ally.
