Can't appoint anyone Sacristan (Chaplain)

[Rikeus]

I created a custom ruler as the King of Duklja (titular kingdom in Serbia) at 1066 start. I made him Orthodox, while the ruler I'm replacing is Catholic. Upon game start, I got a popup saying "[random courtier] is no longer your court chaplain", presumably because he was catholic. However, despite about half my court being orthodox, the list of people I can appoint as Sacristan (which the position has been renamed to) is empty, even if I use the employment decision to recruit a bunch of holy men.

Needs to be a bishop I believe, so you mustn't have any orthodox bishops. Time to "request" that someone convert.

Hmmm, that certainly seems to be the case, although the description of the council position specifically states that it doesn't need to be landed, which is why I was confused.

I think if they are unlanded they need a religious education trait.
