Playing in v.2.5.2.2 (upgraded from 2.5.2) and with CK2+ v.4.04.7 (upgraded from 4.04.4) as the High Kings of Éire, list for setup
here. Slight spoilers below for the "Millennium's Eve" AAR but I'll keep it vague.
Two issues I spotted:
1. I don't see any option for matrilineal marriage, not even in tooltips for future laws. I don't mind having to pass laws, etc., but it was a useful option in vanilla and I'd like to know if it's still an option.
2. I pressed the claim of a courtier. Halfway into the war, they "come" to my court as an adventurer to ask for help to press their claim (!?). I say yes, because I want them to win, and even give them gold.
A while later, they arrive as a hostile army. The courtier is annoyed at me for "pressing a rival claim" - which is for *them*.
I can understand a courtier getting impatient while a claim is being pressed for them, but in my view there should be two changes:
a) If you are already pressing a courtier's claim, a dialogue option to tell them to be patient (or even two - a diplomatic and a less diplomatic one)
b) If they do launch a separate adventurer claim, at least the possibility of allying - since both sides want the same outcome.
