OK - So I'm really still not able to connect when I'm actually able to play.

Many people suggested making characters on JPN servers as a means to actually do anything.
But then I heard a number of people saying they were unable to access their NA/EU characters.

Apparently... I did not express this to my wife - or if I did - I was mumbling.
She made a character on Tiamat yesterday so she could at least do SOMETHING, but our mains are on Gilgamesh.
Now, when she tries to view character lists, NA/EU won't even display: "Unable to attain list"
Funny thing is - I just loaded, and got the same error for JPN server: "Unable to attain list"

Is it actually denying you the ability to view servers opposite your last log-in?
Did this somehow re-register the players as a JPN player instead of NA/EU?
This would be a tragic tip of the iceberg for her, if she lost her NA/EU characters.

Does anyone actually have information on whether or not the other data is retained, and if/how it can be accessed again?
