I have a feeling I missed some quests. I lvled in Pvp and had to go back. I started in war within on my priest alt up to lvl 75, then started my main Warlock. I noticed I am lacking a “War Within” Achievement and this Opportunity Point didn’t appear until after I finished some later quests.
I see others have been having the same issue on this getting into undermine.
UPDATE: I solved the problem. I had to do the Table “Papers Please” quest. Still a bug I think.
