Yep. Spent literally weeks with my girlfriend saving up 7 million Gil for a small house, we went to sleep early just so we could login and get a house. Except for some reason I was completely unable to login, and of course my character has the gil on her, so yep. Weeks wasted. She was totally able to login but for no reason at all I am still as of right now completely unable to login. Great.

EDIT: Oh, and this is after they posted that the login issues have been fixed. So they aren't fixed.
