tenaz and PicturePerfect, we have reported both of those errors to Tor and will give them a new chapter arch image.
CosmereGirl, the difference is due to the recent correction of a continuity error (which I believe was reported early in this thread). The new typo doesn't exist in the new hardcover or trade paperback PDF; the word "saw" is supposed to be "so," but when they were updating the ebook with the corrections they made a typo. I've also reported that to Tor.
