Since last night, the US server Aibatt and the EU server Clockworks have been experiencing massive server issues. The channels 1 and 3 are completely unaccessible. According to player reports the system announcement for upcoming guild house auctions was spammend permanently right before the crash.

During the same night moderator Serabell announced on the English FlyFF Discord server that the issue has been reported. So the situation might be under investigation now.
