What happened to this series? is it on hiatus? or the group stopped releasing it?

It looks like it has been licensed so the translator has stopped doing it. Not sure though.

The series is not on hiatus, nor has PROzess stopped translating it. The series has been licensed long time ago. Yen Press has already released its 4th volume, as well as the 5th volume in digital form.
So far, PROzess has been working only on eBook-looking (good quality) scans, and considering the frequency of volume releases of the actual manga in Japan (5th volume - 2015/3/30; 4th volume - 2014/4/25; 3rd volume - 2013/4/30), basically, one volume each year, and the last chapter released was the last one from the 5th volume, you will just simply have to wait some time until a new release is made. Which, guessing by the frequency of all the previous releases, will be sometimes next year.
I hope that helps you.
