User blog comment:Kindrein/Deleted an article, but I can't reupload it w/ the same name/@comment-25156300-20191227204337

Try it now. Your old page was recently deleted by an admin, but the redirect from when you changed the page name to "Deleted" was still there. It's gone now, so it should work.

For the future, you can just keep old pages and rename them to the new character. That way you don't have to bother deleting one and remaking another.
