Chests are not resetting for at all. Spent a gold jumping to every chest. They are still open been that way for a week. If you are going to put equipment behind events collection at least make sure the events is fully functional. Sitting on 18 keys so far and the chests are not resetting. Love the game, but hate this event idea. To expensive and bugged to boot. ANET you can do so much better than this.
