At the bottom of the Day 0 page, the "next page" link goes to the mini reprohack page, not Day 1 like I would have expected. The previous page on the mini reprohack page goes back to Day 0.
On the main day 1 page, there is no next or previous page link (this applies to the main page for day 2–4 also)
