This update brings with it the end of the Winter Event. Once the update is complete, you will no longer be able to craft special event items like Baked Apples, but of course you will be able to keep any event items which are already in your inventory. All event-related quests will be deactivated and event items will no longer be for sale in the market. Your progress towards any event-related achievements will also not be affected.
