I have been testing these "7 day login win reward pack" and "blizz 7 day reward pack."  After clicking the button and the website stating that the reward is redeemed, sometimes, I receive the reward and sometimes I do not.  This happens very often for me.  I keep track of my item numbers on a notepad.  Refreshing and waiting for a day to log back in, the items are still not delivered.  Then, completing the new day reward and redeemed, the new reward is delivered but the old one is still missing.  Has anyone noticed the same?
