Weekly Quest: Upgrade hero equipment.
For completing this quest, you are supposed to get 40 sketches. You don't I don't believe that the quest has ever given the sketches, but for the last two times I've completed this quest, I know for certain that the 40 sketches were not put into my inventory in the BM.
I'm 80 sketches short at least, and everyone else should check their sketches totals before and after they complete this weekly quest. Because Plarium isn't delivering the sketches.
