Building / Capturing a temple divests your heir from your line of succession

[K-vald]

It becomes investiture and if my heir was heir to that temple then he/she isn't anymore when creating a new vassal. At least that's what happened for me. Do you have any more information on the issue?

Have the same problem. Was playing as Aragon, declared a holy war on OPM neighbor, got all his holdings, immeadiately created new vassals for town and a bishopic. On the next day my daughter (only child) is not a heir any more. I saved a game, reloaded and my daughter is a heir again.

Ok, will try load the save and see if the heir changes.

UPDATE: Nope, the heir does not change on load for me.

Will look into it further with this updated information. Thank you for following up!

UPDATE: It doesn't work for me, I mean, the steps to reproduce. The inheritance works just fine even when making peace with the Muslims.
