Hi,
I've tried to search for an answer to my problem but without luck.
When I import books in Calibre I just MUST have the abstract, serie and number correct (I have a hard time sleeping if I know that there are fields missing...

).
I have found that sometimes (roughly 10%) of the books I've edited now are empty, i.e. only the cover and metadata is left.
I've seen this happening when I change the metadata fields, title, cover, etc.
Anyone seen this?
How to avoid it? (except for just importing the books and leave them as they are)
Bug?
