the data loss has produced some quirks, which aren't really solved completely

1) automatically generated lists are bugged (empty edits in the pages that should be listed help, but nobody has done this systematically afaik - I did for some publishers)

2) some pages are still "existing" for e.g. random page or undefined pages, although they are not in the library - not sure how to handle this. I guess adding and deleting the page might work, but I don't feel particularly eager to do this myself.
