This was just a preview, said by a new translator.
It looks like it is, because most of the time, every chapter is 30-50pages.
But this time, only less than 20 pages per chapter.
So be warned reading this translation.
It probably needs to be retranslated by someone or another group in the future, who will translate all the pages, and not just the previews or some random pages of 40+ into less than 20 pages while skipping the rest of it.
My assumptions would be that this very translation group is only uploading the translations that the MTL successfully translated, while ignoring the complicated ones. Even if the real reason is not like this, be warned. They're ruining the wonderful experience so far.
