It’s happened a couple of other times that I know of. The original is several thousand chapters and the translated portion stops in the three digit range. This one at least made it to ~Chapter 374 (in the RAWS). “Biting Red Lips” stopped before hitting the 150 chapter mark.
Why did they change it from after chapter 509 here (360) in the raws. They suddenly changed it before finishing it in a rush, despite the raw still having nearly 2000 chapters
