How would you outlaw it? It's not a bug, it's bad game design. I can see outlawing abuse of it, but it's a perfectly valid way to generate tourism. The problem begins when you ICS with it. Also, this is very, very difficult to abuse on Deity. Also, sometimes you end up getting Sacred Sites from someone else's religion invading your territory. So how do you outlaw it? Since IMHO it's not fair to outlaw, you'd have to set some sort of max # of cities, or something like that. I do agree though, that for CV on any difficulty below Deity, perhaps you should not be allowed to take that reformation belief for HOF games. Until(yeah right) it's fixed. Not ideal, but otherwise you might as well say: Allowed Victory Condition: Sacred Sites. Prince or below especially... the AI is so pitiful on Warlord.
