After upgrading the Roaring Skyscraper to level 15 the app turns mostly black and white and flickers like a strobe. The problem goes away if I store the building. I deleted the app and installed again from the app store. That did not fix the problem.
Another view of the issue.
I assume this could be the effect which this tower produce. Switch it off and look if all is normally again
That's the whole point of the tower! It creates a City Wide Effect, making your city look like it's in the 1920s.
Tap the building and you'll see an orange button to enable / disable the effect.
