If they didn't, uploading this right on the current's scanlator's schedule without consulting them is a huge dick move tbhThanks for the TL, but next time I would discuss it with the main group first if I were you. You never know, they may have had a chapter ready, and now it's gonna look like it got sniped to them. Most people typically wait 3 months before taking over a series (without first discussing it)
This is just my opinion, of course. I myself have taken over other series from groups before (but for different reasons).
