Lost folders, smart folders and faces.
A while ago I upgraded the Aperture to 3.3.2. After that I noticed that I missed all my faces so I fixed permissions, repaired database and and rebuilt the database.
and then upgraded it to 3.4.2.
Only after having done all of that I noticed that I had lost all my folders and smart folders as well, I however, don't know where in the process they got lost.
I have an old backup but I'm afraid that I have added to much photos since. But I am not so concerned over the fact that I have to recreate a lot of folder, but what do concern me more is that I am losing confidence in the library management.
Could someone help me clarify where in the process these problems can occur and how to avoid them?
Is there something that I should verify myself after certain actions?
Aperture 3, Mac OS X (10.7.5)
