Actually that's been happening all of a sudden again..........according to CN's Forums. Me personally, I haven't logged into FusionFall for a couple of days so I wouldn't know myself. But there are alot of posts stating the "ID" issue.
It happened to me before a long time ago.
What I try to do is when that starts to happen, I usually just give up playing for about an hour or 2, to give the Server enough time to automatically log me out.
Then I just log back in.
This has worked out for me so far. Never had any issues with this method.
