no book covers appearing on wall box

My LivingSocial book profile on my Facebook wall has been acting odd today - first, it shifted from having the "already read" line below the "currently reading" line to only the currently reading, through no action on my part. Then I just added a new book, and the preview shows the cover, but then my actual wall page does not show the book cover. I've refreshed, and still nothing. Are you all working on the app at all today (12/19) that would make things go suddenly a bit haywire?
