When i logged into game after a month probably, I went to get my PvP rewards from season 3 Solo. I had Voucher C in my mail so i grabbed it and gave it to Quartermaster how i was supposed to do. However only thing i got from him was the mount and thats all. No Diamond rating achievment, no diamond bracelet from feast. So i am asking if i missed a deadline to get my reward about which i didnt know or if its a bug. Thanks for respond.
