I don't think they have a schedule, they just update the translation whenever. They've been focusing on the game since the release date is coming up so my guess is that they'll pick it up again once they're less busy
I think you might be thinking that the manga isn't being translated but exists (i.e. there's a chapter 14 or a chapter 13 part 2). There is no chapter 14 out yet, they get translated when they are released.
