this is wrong on so many levels.
please read about "Despotovina" period in Serbian history.
to summarize what we have about "Krstajni so far":
"Krstajni" - official state religion in B.
symbol is cross inside circle

there will be at least 3 levels of church buildings:
1. hiža (small prayer-house)
2. chapel
3. small church
+
monastery
"Gost" instead of priests as campaign map characters which can be promoted to "Veliki gost" (or "Djed"?)
additional buildings that will allow Bosnian player to manage large percentage of Catholics or Orthodox inside his state without them revolting.
so Bosnia should have advantage of being less prone to religious unrest by Catholic or Orthodox subjects. But conversion rate from Catholic and Orthodox to Krstjani should be lower (than other way around).
And i will talk to il_duce about making scripts which will enable Bosnian player to change its state religion to Catholic or Orthodox if he chooses to. but this will have its cost in unrest amongst followers of "Krstjani" religion (maybe even open rebellion of nobility), and advantages of improving relations with Catholic or Orthodox factions.
and money reward from Pope if he chooses Catholicism
.
Changing state religion will have positive and negative sides and player should be very careful with this, and choose wisely what is in his best interest.
