Body: <p>I use three fonts in my ebook. Two of them Sigil is okay with. However, the primary font is kicking the weirdest error.</p>
  
  <p>Every time I validate, Sigil gives me two errors for each member of the font family:<br></p>
  
  <ul><li>The resource is reachable, but it's not in the OPF.</li>
  <li>The resource is in the OPF, but it's not reachable.</li></ul>
  
  <p>That's right. It complains about two entirely contradicting things. So does anyone have any clue what could generate an error like this?</p>
  
  <p>FINAL EDIT: Ah, I managed to figure out the solution. So basically, the opf referenced the font as <code>Fonts/GoudyOldstyle-Regular.otf</code>, but my <code>@font-face</code> referenced <code>../Fonts/GoudyOldStyle-Regular.otf</code>. So basically the name was syntactically correct enough for the font to appear, but the capitalization confused the validator. As soon as I fixed the capitalization everything was bread like butter.</p>
  
  <p>EDIT #1: Whoops. Put a 'not' in the wrong place. I fixed it. And yes, the filepaths check out. It works on my phone via Google Play Books, and it works when converted via Calibre to .awz3 format and plopped on a Kindle Fire. For some reason, it just has major grief about a problem that isn't there.</p>
  
  <p>EDIT #2: I'm actually trying to upload the file through the IngramSpark program, and their validator is kicking a similar error, and will not allow me to progress. Here is the code in the opf file:</p>

Title: I have a weird error on Sigil regarding my fonts
UserDisplayName: Agent Baron
ThreadText: # I have a weird error on Sigil regarding my fonts
  
  (Asked by: username_0 on 2014-11-25)
  
  I use three fonts in my ebook. Two of them Sigil is okay with. However, the primary font is kicking the weirdest error.
  
  Every time I validate, Sigil gives me two errors for each member of the font family:
  
  * The resource is reachable, but it's not in the OPF.
  * The resource is in the OPF, but it's not reachable.
  
  That's right. It complains about two entirely contradicting things. So does anyone have any clue what could generate an error like this?
  
  FINAL EDIT: Ah, I managed to figure out the solution. So basically, the opf referenced the font as `Fonts/GoudyOldstyle-Regular.otf`, but my `@font-face` referenced `../Fonts/GoudyOldStyle-Regular.otf`. So basically the name was syntactically correct enough for the font to appear, but the capitalization confused the validator. As soon as I fixed the capitalization everything was bread like butter.
  
  EDIT #1: Whoops. Put a 'not' in the wrong place. I fixed it. And yes, the filepaths check out. It works on my phone via Google Play Books, and it works when converted via Calibre to .awz3 format and plopped on a Kindle Fire. For some reason, it just has major grief about a problem that isn't there.
