Problem : I never noticed this until I went LICH. The academy building only has a very tiny portion of the blue circle that is selectable when you want to complete research.
The only time the view is correct is right when you get “city upgraded” and then both the academy and stronghold are both visible on screen.
Any other time these buildings are cut off making them frustratingly difficult to interact with.
