AutoCAD Inventor :: ILogic Catastrophic Failure

I have a rule controlled .idw with several rules that call each other and various API macros with views and partslists that all have their own rules.

I want the drawing to close itself without saving the changes after it's done executing all of its code (the end product is written to an excel sheet). Everything works beautiful, and the drawing does close itself like it's supposed to, except for some strange reason it throws an error message when it closes.  I've tried a few different methods of closing it.  The code below is what I want to use.  I've tried it with close set to false as well (saving changes).  I've also tried calling an API macro that's pretty similar looking. They all have the same result. The rest of the code executes just fine, and no errors are thrown if I comment out the code letting the document stay open.

I've even tried making a brand new virgin part, writing a rule with just the below code and executing it. The only difference is the error window is thrown from Inventor instead of windows.
