In my latest walkthrough of this main DAO quest - which is undoubtedly the longest main quest - I have noticed that if you follow the Shifting Allegiances quest which means working for the Bhelen in the first round only to betray him to the Harrowmont in the second and finally I gave the crown to Harrowmont, Bhelen's warriors in the Provings do not actually turn aggro after Harrowmont's coronation and Bhelen's death when you try to talk to them. It is my 3rd walkthrough that I give the crown to Harrowmont, but only the first that I don't work for him from the first round, so I think because of that change, the Proving warriors do not turn on my Warden after he puts H. to the throne.
I'd like to ask you if you have any similar Orzammar walkthrough and validate that the Proving fighters do not attack you as well. That doesn't necessarily involve completing Shifting Allegiances quest but probably just working for Bhelen in the first round and giving the crown to the Harrowmont in the end.
Furthermore, when you cross one candidate for the throne, thus having 2 "Paragons of her kind quests active and picking a certain dialogue choice in the end of the quest (still trying to determine which one), only one Paragon quest is flagged as completed, after you put a king to the throne while the other remains as active. If someone had noticed something similar, please let me know as well in order to add it to the Bug section of the post.
