Legends Maple Golden Fruit disappearing

Is it just me or did Nexon screw up their dates on these little fruits? It clearly says "Usable until 2012/03/03", and yet I popped two open and was greeted both times with a dialog box, "The Legends Thank You Event has ended." This does not happen with the Weapon Box, however.

My free coins!

The event tab said the Growing a Maple Tree event lasts until 2/15/2012... however, that would imply that that would have been the last day. So, the event technically lasted until 2/14/2012.

There goes an easy way to get coins.
