I honestly don't even know what's going on with the releases at this point. From what Yukiyuki said, he took a break from the chapters to work on storyboarding the remainder of the story (we're approaching the ending so he wants to make sure everything lines up), but not releasing anything was making him feel physically unpleasant so he should be starting up again now. Not sure if it's going to last though, I guess we'll see.
For the record, I don't think he's slacking or anything, just trying to balance a lot of plates.
