Beebe's cleangroup.lua and storyboard.hideOverlay()

I used the storyboard overlay function for the first time yesterday and came across a weird error. When hiding the overlay I get several errors from cleangroup.lua (don’t have the code with me at the moment). The weird part is that I am not using the cleanrgroup function inside the calling scene nor the overlay.

If I comment out the cleangroup require in main.lua the errors go away.

Just wondering if anyone else has ran into this or maybe Beebe can chime in on what possibly is going on.
