Im playing as the byzantine empire and i've mended the schism in favour of orthodoxy and now am looking to change to hellenic before i create the roman empire. I've gotten the mystic courtier show up, took about 3 game years for that to happen, but now 10 years later i havent gotten any option to learn his secrets so i can convert. Is this something that just takes a very long time or is it possible to screw it up somehow?
