There's never been a hiatus for Fairy Tail, only Shounen Magazine taking a week off. The scanlator simply wiped out the title for the next chapter in their haste. The next chapter title is "Tartarus Arc Epilogue". So the next several chapters should be aftermath and wrap up for the arc. Though it might be shorter than the other parts, the next chapter is supposed to have 33 pages and color as well, and this part of the arc has run a bit long. So I would not be surprised if it's fewer chapters.
