"From Where" disappears, followed by other issues

When I edited a book today to remove a venue in order to replace it with something more accurate, I clicked "remove" in the venue "pop-up" window, and the "from where?" field disappeared from the main record of the book (the "from where?" header remained, but the field itself and the option to change it both vanished).

I had to go back and re-edit the book to get the field back. That's when I noticed that the "Date Acquired" data had changed to today's date. I fixed the date and added the proper venue, clicked save, and went back to my home page. Now on my home page, the book is showing with a different cover (it's in my recently added books, so it appears on my home page). But when I click on the book to view it, the cover is correct.

Steps to reproduce: Click Edit Book, click Change, click Remove. Field disappears. Click Save. Click Edit Book. Add proper venue. Click Save. Check out home page. Wrong cover.

I'm using Firefox - 12.0, Book is Sense and Sensibility, Jane Austen.

The cover on my home page also changed when I added a venue to other recently added books; these did not have venues before, but when I added venues, the covers changed on my home page.

I had the same issue months ago using IE8 (pretty sure... I've since had to migrate to FireFox for other reasons).

The cover thing _may_ be the old bug where, in Recently Added on the Home page only, the cover only shows if it's the last thing you do. I've usually seen it go to my default cover if I do something after I've added a cover, but I suppose it could go to the standard Amazon cover or something instead.

The rest - the field disappearing - is a separate and seriously weird bug.

I categorized the bug (you do it with the Edit link over on the right, next to Bug).

The "from where" bug is fixed. The cover-image bug has been reported elsewhere, so I'm considering this bug fixed and that open.

Thanks,
Tim
