What went wrong?

Hi,
I test BookOrbit and I noticed I cannot download any GB2 books via OPDS, while EPUB works fine. The link for FB2 is just missing. See the attached screenshots from KoReader. While on this, it would be nice if the system converts the FB2 books on the fly to FB2.ZIP (fb2 file just zipped with the same name). The FB2 is XML file with images encoded in it, so it can become large. That’s why many readers support FB2.ZIP out of the box.
Regards

Steps to reproduce

Set up a BookOrbit, add a FB2 book, and try to download it via OPDS
