(PS4) Shoot the Messenger inaccessible
After doing the third Amita/Sabal choice mission, the Willis missions as well as a new campaign mission, which I'm assuming is Shoot the Messenger, popped up. Since I like to save the campaign missions for last, I did all of the Willis missions first, which completed Act 2. Now when I go to the building with the campaign mission the door is closed and there is no way to enter. I previously got the loot in the building and I remember how I got in, but that door is now closed. What in the world am I supposed to do now? There is literally nothing left for me to collect or complete in the souther region. Did doing the Willis missions first **** me over that bad?
