Attention Maplers, Currently, loot ownership of items and mesos dropped by monsters defeated by another player would eventually 'expire', making it a free-for-all and allowing other players to pick up the items and mesos. In the v.246 update, loot ownership of items and mesos will be changed to no longer 'expire' and will only be lootable by the player who defeated the monster. Because of this change, the Expired Pickup Skill for pets will no longer be necessary and therefore will be discontinued from the Cash Shop in the v.245 update. The Expired Pickup Skill for pets will also be removed from the Pet Boost Package sold in the Cash Shop, and the Pet Boost Package's price will be reduced from 7,000 NX to 6,500 NX. - The MapleStory Team View on the Official Site
