I have had a religious head installed for Haredi (Judaism) for like a hundred years now, and the option to launch Great Holy Wars has still not appeared, despite the wiki implying that I should be able to. It just says "No Great Holy War Called", but the High Priest has no dialogue option for me to request them, nor can I do it from the dialogue with other kings/emperors. Is this a bug, or is there something else I need to do to enable them?
