[2.1] Unable to have physician after creating Iron Throne

I'm playing a game where I started as a feudal count of Westerosi Valyrian culture. It was a shattered realms game with historical titles (count level) and 95% ruins.

After colonizing much of Westeros, I eventually created the "Seven Kingdoms of the Iron Throne" empire title (e_iron_throne).

Since then, I'm unable to recruit a court physician.

This happens because

Here is the relevant code. I've added some custom comments preceded by #NA:

can_be_physician_trigger = {
#liege = { NOT = { religion = jogos_pagan } } #combined with moonsinger

OR = {
AND = {

has_landed_title = e_iron_throne

So I don't really know what to expect given this has no lore background, but I guess a smallish edit would be to set the e_iron_throne_created global flag when the Iron Throne title is actually created if it's possible (i.e. there can be code triggered upon the creation of a title). If this is not possible, perhaps the trigger could be that the character either holds the Iron Throne or is a vassal (direct or indirect) of the Iron Throne.

Thanks for your time and consideration
