In the Simpsons: Tapped Out, the 2nd Act of the Christmas quests 2015 have ended, but my buildings still appear vandalized. I didn't complete all the vandalism quests, but this seems excessive - I should be able to have the option of my fully upgraded buildings without goop on them, since I already checked in a lot for the full upgrades. Is this a glitch or is there any way to clean them?

Thanks in advance!
