Opened app to check event results this morning and results were gone. The results should be visible for all for at least 12 hours.
While you cannot claim tokens for a journey after the event is over (even if the journey completed before it ended, you have to actually log in and get the exploration complete screen before the event ended for it to count), upon logging in, if you had any rewards left unclaimed (like useful caskets), you would get a popup with all of them. If you had already claimed all your rewards though, there is no need for a popup, since the event is over and there was nothing left for you to get.
