Hello,
Related to the Level Achievement Growth Package, the original event duration was set as Mar 15 - Apr 18.
In fact, during the maintenance on March 29, the event has been extended until May 16 (https://forums.lineage2.com/topic/26510-aden-server-maintenance-march-29-2023/).
Given that the event has already been extended for a month, we are sorry to tell you that another extension of the event is not possible.
But as I have gone through all the comment on the forum regarding the Level Achievement Growth Package, I will definitely deliver them to the related departments and ask for a future event to contain the item.
Thank you.
Eva
