There is probably already a thread for bugs and glitches but like many other forums, I don't see anything sticky'd.
So far everything seems good to me but I have discovered one small issue.
Version 1.00 retail
Sometimes when I choose my town to assign upgrades, I do not go back to isometric view. Zooming in and out does just that in a complete top-down view. If I want to go back to isometric, I have to hit 1.
All I do is click on my town and build or don't build a new building. When I choose 'done'. I go back to play in completely top-down view.
