There hasn't been a database wipe since the previous rounds of BR - so any characters you copied over then can not be recopied over until the database has been cleared. If you notice in the email you got confirming the transfer it should have said your characters transfer/copy failed.
I had never copied these before. And the mail says the copy succeeded.
Greetings, ****!
Your World Transfer is complete! Below is the information for your transfer on 9/18/2019 6:04:41 PM:
FROM WORLD: Ithil
TO WORLD: Bullroarer
Other details:
Character copied: Laergwend
Character copied: Frostbyte
Also, I went to the NPCs that vendor the gear in Ox camp & Stangard, even checked quests rewards in Dunland. All of them look exactly the same.
