Aperture photo adjustments have disappeared
Running Aperture 3.6 on a MBPr 10.10.2.
For some inexplicable reason some photos in an Aperture project seem to be missing all adjustments/edits I have done. What's even more weird is that these adjustments are still visible in "Browser" view mode but not in viewer mode. For instance some my black & white images appear B&W in browser view until I click on the image. Then for a brief moment, the B&W (edited image) gets loaded (and shows as B&W) but quickly reverts back to its original state, sans edits. Exiting this viewing mode back to "Browser", I can see the edited image again 😠.
I've tried exporting the an image (version) to the desktop only to find the original image was exported.
I've tried repairing permissions and repairing the database for Aperture (command-option when starting the app). Nothing. Any suggestions on what the issue is or how to correct it (short of editing all the affected images I mean)?
Cheers,
Mark
