SoC Cyclone V example design : error->hierarchical path is too long

I recreated this on my side. I'm not sure how this happened but it's a valid error because when I look at the heirarchy it's ghrd_top --> soc_system:soc_inst --> ghrd_top --> etc... (just keeps repeating).

The issue seems to be the top level file instantiates soc_system which then instantiates the top level file which causes this vicious looping to occur. Did you modify the project since it looks like a human caused this and not the tools?
