Hey there,
I just saw that I did not receive any rewards for my PvP result from last week. This time I am sure and I think it was the same last week. You can see it easily If there is a red number at the menu button for the BoS, as we should be rewarded with Souls and fragments! This time I also tracked the number of Fragments and they did not increase. Is this happening to all of us/some/many, or only me?
