So I was just playing the mod for the first time and decided to play as Rhaenyra.

Sadly Daemon died within 2 weeks, so I decided to focus on building alliances to prepare for the probably scripted civil war. I went with Domination life path to keep my Vassals in line, married the prince of Dorne to get a strong ally, Married one of my kids off to the Tyrels, made sure my Spouse likes me so I can pop out as many children /dragon riders as possible.
Forced her dad to give me the Marshal council seat.

Whenever I checked I was the primary heir, even had an event pop up at the start where he ensured I'd remain the primary heir.
So I was just doing my own thing waiting for him to die, conquered the Stepstones and made myself Queen of the Stepstones and then when I just casually check again I'm not the primary heir anymore. Completely lost all my claims to the Iron throne.

So the question is:
Has anyone any Idea why that could be? Is it the Vanilla game overwriting some game script, or will the Dance of the Dragons fire as an event anyway once the old man kicks the bucket?
I'm just wondering if I can still expect some kind of scripted event to trigger or if I should now focus on eradicating my half siblings the old fashioned way?

Cheers.

Edit: So yeah nothing triggers after the Kings Death, so I guess something broke along the way.
So I guess I finish conquering Essos for now while undermining the other family branch, lol.
