Yeah, I read the message "once you start a character, you can't unlink this account." No, I should be able to. I couldn't find my Windows Xbox account at first, then I finally found it, which I paid for stuff already on. I want to delete my Steam account and start over. That should be my choice if I paid for the game.
This is the worst thing I've ever seen on any platform, obviously the Windows version has problems, so I don't want to use that one anymore. This should be a major exception.
