I've now checked the folder where the images are, the .xmp files are there, so when I look at the files in photo mechanic, the crops and edits appear to all be there and correct, but Lightroom isn't seeing them? I'm going to try converting all NEFs to DNG's and see if that helps.
Lightroom doesn't use the edits in the XMP file. It uses the edits in its database. So the presence or absence of edits in XMP is irrelevant to the way Lightroom displays the photos.
Now, in your case, if for some reason, the edits are not in the database, you can force Lightroom to read the edits in XMP by the command Metadata->Read Metadat from Files.
thanks dj, I understand that, the crops were recorded in the amp's nothing else. It looks as if everything I did in a 2 1/2 hour period was not recorded in the LR database going by the timestamp on the restored .lrcat file. I had been working on different images earlier with no issue. Then I went through the game folder and edited. LR appears not to have saved those changes. I had made no changes to the preferences, so I am at a loss to understand why the LR catalog has not updated. (while I working on them, previous ediits, flags and stars were seen by LR
I tried "Read Metadat from Files." and it seemed to work, but again LR crashed when trying to use publish services. I am restoring from an earlier backup, and will; try again, thank you
