Righteousness raising dropped from 5 to .5 stars overnight?

Righteousness is a fickle is a fickle stat; it's supposed to be based off of vandalism, tapping Sideshow Bob, but often you can see some weird behavior like what you're getting. It worked poorly before and but it seems to be worse with the Sideshow Bob gone and during events.

If you're worried about it, really the only way around it is to build a lot of training walls. A lot of people do this since it's the only spammable decoration that gives you righteousness. You can then hide them behind taller buildings.
