Has anyone experienced, that every building of your state religion gives a bonus of +2 production?

If so, what triggers this?

Cheating?
Events?
Other?

My roommate gets it many times, and I'd most like to think he found a cheat.

Buildings of the AP's religon have this bonus. Unless you defied an AP resolution, that is.

That would be caused by building the Sistine Chapel.

No,thats culture.

The production bonus is AP i think?

The +2 :hammers: bonus most definitely comes from you or another civ with the same state religion having build the Apostolic Palace.
