Has anyone seen these lines on cc objects before? -pic-

Hi. They are split edges. It is best to not rely on edge split modifier and split only those edges that you need to be shaded as sharp manually
- In edit mode select everything with A and Remove doubles with Merge distance set to 0,0001

- you can select everything and Select - Sharp edges, adjust the angle until most or all of the ones that you need are selected;
- Mesh - Edges - Mark as sharp;
- Alt click on those edges that you do not want to be sharp, holding Shift, select all of them. Mesh - Edges - Unmarked as sharp or something like that;
- select one edge marked as sharp, Select - Select similar - Sharpness to select them all. Mesh - Edges - Edge split
