Sudden disappearance of items from lists

[seabelis]

Items have disappeared from lists without being deleted. It's suspected that editing a list on testing.openlibrary.org may cause the issue.

Maybe related to adding new books to the list from testing.openlibrary.org.

[cdrini]

The leading hypothesis is that this is related to adding books to a list via testing.openlibrary.org ; this is a known bug with testing.openlibrary.org and staging.openlibrary.org . In a nutshell, if you make an edit to a list on production openlibrary.org , then try to add another book via testing, because testing.openlibrary.org has its own cache, it will have an outdated copy of the list, and add the book to the old version ; so the book you added on production will not be there.

It's still not entirely clear, but I tested adding a book on production and didn't see any issues? But the librarians use the lists more, so please let me know if you hit this issue again!

Haven't gotten any reports of this anymore so thinking it might've been the testing issue.
