I noticed the other day that none of the ratings I've made in Aperture are showing up anymore.
Firstly, I'm wondering how that could have happened? I've done a number of things lately like relocate masters, regenerate thumbnails, etc. but I can't pin it down to a specific date and besides I was fairly certain that the ratings metadata was stored separately from all of that. I'm trying to avoid having to restore the library from Time Machine.
