I have found a bug (or glitch) with the great people. I play just a regular game on the epic timetable.
1. I was able to get a golden age by using two great prophets, and only one of them was sacrificed.
2. Everytime my capitol gets a great person the point counter in ALL cities changes. For example, my second city has never produced a great person becuase it is getting less GP points than my Capitol, and the total needed in city two keeps changing to match the point total in city one. City 2 needs 900 GP points now to produce its first GP.
