Okay. First thing, i was editing a building and the great works finished while I was so it, the only option was to click "Ribbon Cutting" so I did, and when I returned to my city. There are two rows of buttons. One is always the great works/regional buttons and the other ones are the cities buttons.
Also, I can't switch from this city to other cities in the region. I can switch from a different city to this city, though. The button problems only happen in one city.
