I have Aperture photostream turned on and set up to automatically import and upload my photos. For some reason, about two weeks ago, Aperture stopped importing my photos. They still show up in the Photostream, but they no longer get imported into events, photos, faces and places. They used to automatically go into a folder called Mar 2011 photostream. I'm not sure why this has happened, nor what to do about it to get it corrected. I can still manually drag the unimported photostream photos into my Aperture Library, but I'd prefer it do it automatically like it is set up to do and supposed to do.
