Currently I'm in the middle of the Cultural Crusade quest with my Peteran priest as the primary hero and my Wizard as the secondary. I've progressed to the point where the Wizard has succeeded in getting four Sims to attend the priest's next sermon. The priest gave that sermon as scheduled but his goal of giving the "sermon on waning faith" still remains. I was wondering if there was something I'm missing here--the pulpit doesn't give any options other than "Set Sermon Time" and "Give Sermon" once the scheduled time arrives, and clicking on the priest doesn't give me any options relating to giving a sermon, either.

Anyone got any hints for me about this..?

It should come up as an option on the pulpit at the same time as the normal sermon is set. Thats all I know, Im afraid.
