Here's a small, but nasty one. It's also kind of hard to explain, but we'll try.
Thanks! Good to hear of all these bugs being fixed.
I wonder if this is related to (or exactly) the bug I've run into often.
Problem: I want to release a book but the available release zones do not match the site I have in mind, so I create a new release zone. I release the book. If I now want to release another book at the same zone, the new zone doesn't show among the available zones for that city. It takes the system a good few hours (but normally within half a day) to show the recently created zone. (I have found the same problem when I create a new zone and upload a zone picture to it immediately. The created zone doesn't list for half a day, not even for the first book. Nowadays I create the zone, release the book, and only later upload the zone picture.)
Current workaround: If I then continue the release process without selection a release zone, I get an error, indicating that I should select a zone. Voila! The zone list displayed after the error message now includes the new zone, and I can select it and release the book.
Is this the same bug or a related one?
