The FlyFF team at WEBZEN announced a double event blessing in a Facebook post today:
Starting on 05/08/2020 at 7 a.m. until 05/12/2020 at 7 a.m. (UTC), a double EXP event will be implemented. Additionally, the droprate of all event items will be increased. According to a statement made by GM Piccolo on the German Discord server, this increase is supposed to be doubling as well.

While the Facebook post does not elaborate on the reasons for these planned events, the Discord announcements shed some light. With all the connection losses and server problems of the past days, it was apparently deemed a brilliant idea to compensate the situation with events… while the server problems still persist and will probably see an increase due to the player load added by the planned events.

Meanwhile, the reasons for the server problems are still being investigated. As of now, no official announcements concerning the persistent issues have been made.
