Ha ha ha, how naive of you to think the uploader made a mistake. Uploaders are constantly re-uploading chapters that are already done. You ever get a notification, then find a story that didn't have an update? It's because they are reported as duplicates, and mangago removes them before you read them.
...what?
Really?
Sometimes the story posted belongs to another story, but yes, there has been an uptick in stories I've reported that have had duplicate chapters posted.
THERE ARE NO NEW CHAPTERS, MAYBE A MISTAKE FROM THE UPLOADER, BECAUSE THE THIS IS JUST RE-UPLOADING
