I partly leveled a "guest" character while waiting to get in contact with Trion to regain access to my account. Now I have access to my old characters with proper login, but I must login as guest to get the new character (then only that character shows obviously). Is there any way to get the new character "attached" to my old account? I'm not talking shards here, literally login.

I tried to register the guest character in game to my account email, but it says "already in-use".
