I looked at Content on the Amazon website and it appears that the books I purchased were all deleted, but they still show up when I use the search toolbar. My guess is that Amazon deleted the original books and then reuploaded them but never linked the old purchases to the new upload.

Regardless of why, I'm not sure if there is anything JNovel can do about it, my fault for buying from Amazon I guess. But I thought I would bring it up if there is a fix.

I'm not going to list all the titles but for a selection, the entire "Ascendence of a Bookworm" series but not the side content (Short Story Collections, Fanbooks, and Hannelore are all fine), "Crest/Banner of the Stars", "The Faraway Paladin" LN, "Full Metal Panic" (Main Series, not short stories), and "A Wild Last Boss Appeared" LN.
