I never get anything good doing a box at a time, so I made the decision to stockpile my seals and then turn them all into boxes and open at one time. I intended before I logged out last night to go do this, but forgot. Every other event where we have collected stuff, there's been an NPC that everything could still be turned into for a week or so afterward. I knew the event was ending, but I didn't realize the entire thing would disappear off the map completely. I have 171 unspent seals, is there an NPC somewhere I don't know about where I can exchange them?
