Steps:
Was disconnected by the servers going down on Friday while attempting to access a retainer (retainer list never popped up). After emergency maintenance finished, tried logging in, could not.

Login screen shows ???s for this character only (other characters can login fine). Attempting to Retrieve Character Data or login with this character results in a 1016 error code "Could not obtain world data."

Attempting to connect to Another World results in 3306 lobby error, and FFXIV exiting to the desktop.

This has been ongoing since Friday.
