Or the endless filler. I think I even know what happened with it.

It appears to me that when they were trying to give the manga enough time to get way ahead; they got sooooooooooooooo deep into filler; that they completely forgot where the hell they are in story for awhile. And now that they do; they're trying to figure how the hell to get out of the mess they got themselves in.
