(I did try to search and see if this was already posted, but I did not see it.)
I completed A Light in the Darkness alone several days ago, and chose the ‘suffer’ fear at the end of the mission. I am certain of this, as I am on my third level 80 character, and I chose the other two fears on the other two characters, and wanted to see the third one I had not yet chosen.
Just now I completed Forging The Pact with another player (who chose ‘letting an innocent die’ as their fear in the above mentioned mission), and as there were no choices to make in that mission specifically, I felt safe in taking the reward. But now, my next story mission is ‘Tower Down’, and not ‘Striking Off the Chains’, as it should be.
Is there a way to fix this, or is my personal story now tainted by playing with another player and taking the reward from a mission that had no bearing on this choice?
