i think it has something to do with the admins on here erasing their credit.
look on chapter 168, page 2 at the very top to see what i mean.
as for why they skip, they say they're only doing the chapters they have in-hand. which means they probably dont have the chapters for that arc, who knows.
they said if they have time, they will go back and do it.
all these vanilla readers crying about dropping this, cyaaaa, you'll sorely be missed (said no one ever)
