Thanks for the chapter.
Personally have no clue why the scanlation groups change every few months, it seems popular, or are people beginning to dislike the series?
EDIT: As for the quality of the latest translation, personally I think it's exceptional for your first scanlation - lots of the newer scanlators seem to have problems with English grammar (falls under proofreading?), which can result in chapters being incoherent. I didn't find that the case for this scanlation.
