Solving Bug in Daily Task, "Make Springfielders preach their version of Christmas"

I'm on iPad and it froze when I sent her on it.
Specifically, the popup was brightened; the surrounding screen was darkened; characters were moving; tapping did nothing.
Within about a minute it had unfroze itself and I noticed the task is greyed out and I think it said, Requires Rev Lovejoy.
So won't do that again.
