Oh I thought I was reading flashbacks of the previous chapter and almost complained why they dragged the friendzoning for another chapter. Then I noticed it was something I already read.
Thanks for picking up this series. In my opinion you should just leave the machine translated chapters untranslated. It's a lot of work, and I don't think that many people will go back to read those chapters. I'm not sure that many people know or care those chapters were machine translated. You'll probably be able to see for yourself the level of support you'll receive for those chapters to be translated, so I guess my two cents don't count for much.
Personally I find that unless the previous translation is absolute garbage, or if it's so off it's hard to understand, it's not worth the effort to translate the same chapter again. Good quality is nice and all, but new chapters are better.
i think you shouldnt bother re-translating the previous chapters. its only a few and the uploader did a good enough job that the story was able to be followed. i think what's more important is the new content.
Personally I was waiting for The Abandoned and have not read the latter half of the most recent chapters yet, so please do announce somewhere whether or not you will redo those. I would prefer to wait for your releases if you will.
You could do what Misfits did where you train new staff with the old chapters and focus on the raws, or just do until you catch up to the raws and then go back. Don't think anyone here would be pressed either way as long as new chapters come out.
