I found a Zoning Regulations.cga rule from 2012 that I wanted to modify for a project I'm working on in CityEngine 2016.1. I made the adjustments and now the file produces an error any time I click on it in the Navigator pane. I'm not sure what is triggering the error, but I assume it's from something in the code that may have been deprecated in later releases of CityEngine. Is there a way to check for that? And if I'm wrong, does any one know why this error would be generated?
