I'm pretty happy this got translated and it seems you have contacted NASS.
However just make sure u get a reply first before doing chapter 16.2 otherwise you may be accused of sniping since it hasn't been 6months+ that the group's hasn't uploaded.
I think you should leave it for the OG scans group, it seems they upload regardless of if someone else uploads the chapters and last upload was a month ago and their scans are higher quality too. Its worth the wait
