(Never mind, I was unaware this only applies to the "Packs" you get when purchasing CE. The graphical glitch still stands though.)

Sometimes I see 2 items go into my inventory via the little animation in the lower right when opening an anniversary prize box but I only get one in my inventory. The animation over my head and the dialog after the box "opens" also only shows 1 item. I haven't actually gotten "double" prizes yet. Is this a problem with double prizes or just a glitch in that animation?
