Sigil conversion doesn't pass Flight Crew

[mrmikel]

I have been working with a Project Gutenberg HTML book. I strip out the javascript and it converts and displays fine.

When I run it through flight crew I get three errors, two of which I think I can fix (language element missing and title element missing) and the third I can't: theislandofsheep.epub/OEBPS/Text This resource is reachable but not present in the OPF <manifest>.

It consists of only one item, the text. What is going on here?

This is the content.opf:
<?xml version="1.0" encoding="UTF-8"?>
<package xmlns="http://www.idpf.org/2007/opf" unique-identifier="BookID" version="2.0">

This was fixed in FlightCrew. The fix will be in the next release.
