All current chapters (up to 52 at the moment of this post) will receieve a re-upload based on the second editing pass currently in process. I've heard back from one of the three volunteers assisting me in this task and integrated the appropriate changes to my master document. When I receive the drafts from the other two, I'll do the same, then prepare the files for re-uploading.
In the meanwhile, chapter 53 will be live soon.
