Hey folks, quick hotfix today, coolest thing is adding Yowie to chests!

+ Adding Yowie's Egg to Greater Glacial Chests
+ Buffed up Leaderboard reward banner
+ Adding Hearthwyrm's Hunter Badge Recipe to vendor for 125 tokens (will not appear on vendor until the Hearthwyrm portion of the event is live)
+ Greater Glacial Chest now correctly checks for a recipe from the 2016 event not 2015
+ Fix typo in frost fiend daily quest
+ Fix silver tier winter banner pointing to last year's gold tier wearable.
+ Fix fire bug elixir popup
+ Double offers have ended
+ The Hearthwyrm portion of the event has been turned on! Find the egg from Syrillax, open up your Dragon Flamestones, and battle the Hearthwyrm!

Stay warm out there!
