Hello there[url=https://tuxydoh.com/images/hi.gif],[/url] A name reset to default like that means it was detected or reported, reviewed by Bungie and reset to"Guardian####", that indicates that some part of the name broke the [url=https://www.bungie.net/7/en/Legal/CodeOfConduct]Code of Conduct[/url] or the [url=https://help.bungie.net/hc/en-us/articles/7648312251284-Bungie-Name-Guide]Bungie Name Policy[/url], was filtered, and [b]can no longer be used.[/b] When that happens, you get the new name cross play message in-game as notice of the name change. You can try [b] a different name if you have not previously changed it.[/b] If the system is not allowing more changes, there is no way to override it. What names have you tried thus far?
