Just passing on an issue from over at GameFaqs. It seems some players can no longer purchase Shadow Jago, eventhough he was supposed to be available until the 15th?

“When I search for Shadow Jago on the Xbox Games Store the only search result says “Bundle Only” and when I click bundle nothing comes up. I tried contacting the support on xbox.com but they couldn’t help me. They said that it’s probably purchased from within the game, but I can’t find where to buy Shadow Jago there either. Where is he?”
"I think they took him down early?
the end date says 1/1/5/2016
so maye they took that as 1/5/2016 by mistake."
