Lightroom: Catalog metadata loss

I have a serious data loss bug here.

I think this has happened before, but I never was quite sure, since it's impossible to keep track of what metadata each of tens of thousand of images does or does not have. But this time, it's 100% sure.

1. I annotated my lost shoot at my office. Added copyright, location metadata etc.
2. Added ratings flags, then made adjustments to keepers.
3. Exported the shoot as catalog, to sync to my home computer.
4. Next morning I came back to my office to find out that copyright and location metadata is missing. However, the adjustments and ratings are there in the catalog.
5. To check that my mind is not making things up, I plugged in my flasg stick that still had a copy of the catalog exported in step 3: the copyright and location metadata is there.

Of, course I cannot reproduce the data loss per se, but what I do have, that I think might help developers, is a copy of the main catalog with missing metadata and a copy of the small exported catalog that does containg the lost metadata. I cannot sync back the small catalog into my main catalog, because Lightroom tells me the metadata match between catalogs, while I can clearly see the difference in the metadata panel.

I'll be happy to provide a copy of both catalogs on request.

Hmm. I'm not sure if the catalogs will give me a hint about how the mismatch arose, but if catalog import is claiming they match something is definitely confused that's worth sorting out. If you zip the catalogs, how large are they? If they're each under 100 MB zipped, transferbigfiles.com or yousendit.com could be used to send them to me. My adobe.com e-mail id is dtull, if you want to send them along and I'll see if anything jumps out at me.

Damn! Sorry for wasting your time, but that was my mistake.

The second, smaller catalog, was missing the metadata too. So, Lightroom compared the catalogs correctly.

Still the metadata loss part of the post is relevant. I couldn't have messed that up, because I have a Beardsworth-style smart collection check list that does not let things slip through my fingers.
