P: Book Module – Unfinished book vanishes

When I am designing a book, and then need to do something else in LR, when I come back the changes are either lost completely or the layout changes are saved but 60% of the images in the book have been changed around / duplicated on other pages. Why can't I save a book so nothing happens to it while I do other things?

Its in this list, posted 11 days ago with title: lightroom.book module a real mess

It may be helpful to say where this report is.

I have had serious concerns about the blurb and book module and |i set these out in a report which has not even beed acknowledged. Seems its low priority.

I have exactly the same problem except I have already installed 4.1RC which was supposed to have fixed this issue. I recreated a book in 4.1Rc and instead of the book vanishing the program replaced the images with others from my library never even picked for the book. Very, very frustrating as i have now lost two full days of work.

In Lightroom 4.0 I was editing a photo book. When I reached page 25 or so, at the attempt to insert a photograph to a new page, lightroom stalled for some time and the book was gone. Any attempt to open it would only bring up a blank book beginning, although in the film stripe below all photos included in the missing book were marked with their number of appaerance in the book. For days I tryed everything I could think of to recover my book, without success.
Although everything had seemed to be quite straightforward (I have some experience with BookSmart) I thought I might have made some mistake that caused the disappearance of my book.
So I studied the book module manual and started anew, being carefull in all activities to build up the book again. And again at page 27 or so it disappeard under similar or identical conditions.

Yep, the same thing that Malcom describes has been happening to me.

When working in the book module, moving from book to book or from book to another module, causes one, two, or sometimes all of my books' contents to vanish. Poof!

Not fun.

Lightroom 4.1 still does not save changes in books.
I edit an existing book, then once LR4.1 is closed the changes seem to be lost.

I'm working on several book projects and finished two successfully. Now when I flip over to another book or library to copy, move or paste something I loose the book I'm working on. After a bit of research I'm not alone. Here are links to folks experiencing the same issues:

I've lost five hours of work today. Beginning to loose faith and trust in Adobe!
