My server is Official Server #1509. A few days ago, I transferred my character from Isle of Siptah to Exiled Lands.
After today’s update, the server ping has been constantly over 300 and I usually cannot log in. I managed to log in once, but my character was no longer my original character. It appeared as a level 1 character with a different name.
I did not delete or recreate my character. Please check the character migration/account ID mapping for Official Server #1509.
