The mission for Barrow Dyad, Derealize, Has been removed in Edge Of Fate, leaving the exotic impossible to obtain, or if you already have the exotic like I do, The catalysts are impossible to obtain. I really hope there is some plan to bring the mission back and with it a way to obtain these things. There has been no real signs of it returning in any capacity as of now and if there are plans to bring it back it would be useful to communicate that to the community. There is also no way to change the taken divergence trait from the multi target or single target modes. I will also add it is taking great restraint to NOT be outwardly frustrated while pointing this out, Due to the overall lacking and disappointing state of the game and story.
