FINAL PREMIER BALL: Niantic announced late yesterday that they are aware of this strange glitch. Until the glitch gets fixed, Niantic is awarding an extra ball as compensation. For those unfamiliar, the last Premier Ball awarded after a Raid will never catch the Raid Boss.
"SHINY" ZAPDOS: The difference between the normal and Shiny colorations of Zapdos isn't easy to see when you aren't looking for it. Basically, Shiny Zapdos has a more orange coloration. It seems the people at Niantic also have trouble spotting the difference. All Zapdos, although not Shiny (as evident by the lack of sparkles), display the Shiny model. This is clearly a mix-up in coding, and all Zapdos will likely revert to normal once Niantic corrects this.
