We have discovered an issue with the "Intense Power Crystal" you receive from bosses.*The "Intense Power Crystal" meso value is lost when*your character has been*logged off for a period of time and the item cannot be sold.*However, the "Intense Power Crystal" can still*be dropped and will expire correctly. Please make sure to exchange this item with "Collector" in the Free Market*before you log off your character to ensure you get your meso reward.* This will be corrected in the next maintenance.*We apologize for the inconvenience.
Sincerely,
MapleStory Team
