Photo loss from a project when creating a smart album
Running Aperture 3.4.3 on iMac with OS X 10.7.5. Photos stored on internal drive. After creating two smart albums based on a date range, one with keywords and one with ratings, some, but not all, of the photos that appeared in the smart albums disappeared from the original projects (each project contains photos from a single day). One of the original projects still notes 454 photos under its thumbnail, but when opened only displays 308 photos. The project path of the photos in the smart album still references the correct project. I tried deleting the smart album but the photos did not immediately reappear in the correct project so I undid the delete. I tried closing and reopening Aperture. I tried system restart. No luck. Reading the Aperture help/manual suggests that the photos should remain in the original project.
