Battle of Thanksgiving and CORNUCOPIA

Yes, they were limited time. But how far into the quests were you? There was a glitch when the update was released on Thanksgiving, or maybe it was Friday, but the quests did not trigger. They did a hot fix on that and re released the update. But it you complained that it prevented you from finishing because you could only download the first update, then they may be able to help you get some of the items, like the cornucopia. I know it is a long shot, but you could give it a go. Good luck.

yes sorry man but as stated in the walkthrough that part of the questline was to be completed before the 29th at 8am GMT (when the SCC one started). bummer
