We'd like to inform you that all servers are now back online, and accessible for each one of you. However, the technical department is still working to pinpoint the exact problem that causes the instability and the inability to login.
In that, keeping your character online instead of logging off is recommended. We'll keep on working to solve the problem as soon as possible, for good.
For more information, please stay tuned to our official site. Thank you for your understanding and patience!
