This is possibly one of the biggest and most idiotic flaws in any stock app. In "Photos", if you want to consolidate a group of related or similar photos into their own separate album, after you copy them over if you try to delete them from the original album it deletes them from the new album as well. Wtf? This makes absolutely no sense at all, why would anyone want duplicates of every picture? Anyone else frustrated by this completely obvious and unnecessary flaw?
