Assembly "Layout Sketch" question?

I have an Assembly Layout sketch that is going to drive all my components. I then have another sketch in that same assembly (that is NOT an Assembly layout sketch...obviously) that is linking to that top level layout sketch. I did (2) full assemblies using this method with ease. No problems. I copied that same assembly and wanted to add some more detail to the sketch.

All that for the question....

I go to edit the sketch and now my assembly layout sketch isnt visible. I even right click on Layout Sketch and click "Show Layout" but nothing. Its very annoying! Anyone have a fix for this problem? Or is this a glitch?

thanks
