Because the previous scanlation wasn't very good and we're planning on doing the rest of the series with the same translator who worked on the first volume.
Since I bought the raws and didn't want to just do ch11+, we decided to re-do the whole volume instead.
I'll gladly give you a few interesting soundbites, all the while burning plenty of bridges (as per usual).
But yeah, I wouldn't mind talking about all things scanlations.
