Hello, I seem to have stumbled upon a rather peculiar bug.
Bug description:
Independent of using an Obsidian-made legacy, a custom made legacy or imported from PoE1, Falanroed will not have a seat in the captains council in Dunnage, and Ferrante will call you a Dragonslayer as if you killed Sefyra in PoE1. In the imported PoE1 save, none of the four possible dragons are killed.
Steps to recreate:
Create a new game using 3.0. Import, create or use any legacy.
