Thanks. I was afraid that was the case. My Dhimini are going to be real pissed off! Oh well.This agenda has a bug. It can appear in situations in which there is no valid province for it. To appear there needs to be a heathen province that can build a temple or cathedral(or whichever name is used in your situation), but the selected province has the additional requirement that it must be a full core. If you have no such province at the moment that the diet event opens, you won't be able to complete the agenda.
