I restored from a back-up, and at first thought it was an older backup because at the bottom of my camera roll are pictures from months ago. But as I scrolled through the album, there are photos from as recent as last week now in the middle, with older stuff at the top and bottom. It's seemingly so random, and I can't figure out what I did wrong? Is this just a bug I'll have to live with from the restore, or is there some way to fix it?
