Can somebody explain why maple leaf exchanges expiring with maintenance were not updated on the event page? Does PA believe people are paying notice to a few times of in game message spam during an AFK event, of all things? That too after the horrifying spamming of upcoming calpheon ball in-game messages The only way I got to know was a Reddit post that too after maintenance started. 

Normally items like Maple Leaves can still be exchanged later with the NPC after the event has ended.  The quests are gone, but the exchange option (Cron exchange for instance) remains.  I figured that was the case here, but it wasn't.  Probably could have gotten 200 Crons.  Oh well.

agree they really suck with that, normally they wait another week before to remove event items, this time maple leaf just go poof
