No problem for our time. That's what your subscription is for!
For the missing comments, try going to
Facebook's Comment Moderation
tool. See if you can find some of the comments that were from the page you're trying to debug. Then, if you click the date (it's a link), that will take you to the page the comment actually came from. That should be the href parameter you're using for your comments box to show those comments again.
If that doesn't work, or confuses you more, just let us know!
Thanks,
Alex
