I redid and old comic and when I was switching it, the pages was deleted and was put up as a new comic screwing up the order of my comic. How would I put the page back to where it is without deleting every other page and getting rid of the comments people have made?

In the list of your pages, each page should have an orange up and a down arrow in its row. :) Click the down arrow for the comic you want to move back into the list.
