So bizarre. It's worked flawlessly for months. Today - when I go to "Composition" > "Add to Adobe Media Render Q"... it only exports one piece of art from the composition - as though I manually selected the one element, and exported from it - which I most certainly did not. Over, and over... no matter how many different ways I try to export it, save it, render it, etc - same result.
What am I missing? Super frustrated.
