Righteousness raising dropped from 5 to .5 stars overnight?

I have a stupid number of training walls hidden because of this. I've now banned my friends from tagging my town or they get dropped, which I tell them from Day 1.

Also:

Send your criminals to jail or to face a lineup often - don't let them commit crimes

Keep Snake under control, he's a one man righteousness killer

Used my THOH currency to buy loads of walls which helped (as did the spooky trees and bushes for tree hugger rating)
