Patch 6.18 brings a number of additions and refinements to the game, including the Data Center Travel system and the new Japanese data center, Meteor.
Notice Regarding the Patch 6.18 Maintenance:
Players who logged out in a World that is not their Home World prior to the maintenance will be automatically returned to their Home World upon logging in.
Due to the number of players, there may be congestion issues immediately after the maintenance, so transfers may take some time to complete.
Should there be a need to restart the game during transfer, players will still be in the queue until the transfer process is completed.
The transfer process will not be interrupted if players minimize their screens.
If the target World is congested (e.g., due to login rush after maintenance or when logins are concentrated), that World will be temporarily disabled as a destination.
