Greetings. You're experiencing a server-side issue, unfortunately. Most likely caused by the fact that you logged out but missed to close the client. Anyhow, your character ID is still logged in on the map server, so get double indentified. You'll have to wait for a crash/manual reboot as there is no other way to get rid of your issue. Keep being patient and enjoy your game. Sorry for your inconvenience.
Best regards
