I am using Aperture 2 on my Imac running OS 10.6.8. Lost all the metadata (with keywords the exception) as well as the captions, and the stack organization was disrupted on the first group of images imported into an Album residing within a Project. This occurred when I imported a 2nd group of images into the same Album. The 2nd group of images did appear in the Album in the correct stacks and with the metadata applied at import. The images are all referenced as I have all my masters stored on external HD's. I have set up a 5 level hierarchy within this particular project as follows: Project, Folders at levels 2-4 and then a series of Albums all at level 5.
My 2nd question is can you auto stack on image import into a project, or should this be done after importing.
