Ubisoft,
I heard that when you play the year 2 content that when you play any missions on Challenging or Higher that no Superior or Purple loot is meant to drop, if this is the case then why did this happen to me today in various missions today.
As you can see if Massive claim their coding is to prevent this from occurring then it is fair to say this is a bug and not an undisclosed feature as this is the exact opposite as the #SotG team has communicated to the community.
