I have a weird inheritance issue - my character is celibate* and childless, but has a child (half-) brother. But for some reason, my heir switched from the brother to a very distant cousin (who should be second in line). For some reason, the brother is also listed as the heir to an Arg (=Castle/Barony - not a temple... and even a mosque should not disinherit him), to which I am the heir in the character view (even though there are vassals in between)
Agnatic Open, Sunni - since I have no children, it should default to primogeniture...? And previously, my brother
was the heir.
* that was the first weird thing - he wanted to join Bektashi Order, and it said this would disinherit him - I accepted because he turned out Dull and Deceitful. So he joined the order, became Celibate... and inherited anyway. Would I have had to land my other son (now brother) to really prevent that from happening? Does Bektashi Order not actually disqualify succession?
It's ironman, so I think I can't use recalc_succ.

I do want my brother, the last (other) member of the main branch of the family to inherit, not some guy from the
other branch 7 generations removed (even if he is strong).
Edit: reload fixed the problem - maybe I would have had to reload before the father's death as well. Now I just need to hope brother lives to adulthood and sires an heir before distant kin guy gets any fishy ideas... or acquire some lustful wives with high intrigue.
