Description

I'm experiencing an exception in the RouteEdgeWithGroups() method: line

throw new InvalidOperationException(); //cannot find a path

is executed in a very complex graph.

I don't understand the meaning of this method; it is supposed to draw edges, but "WithGroups" is not clear to me.

Research direction

Start with SdShortestPath.cs and inspect RouteEdgeWithGroups(), especially the InvalidOperationException at the reported line. Reproduce the failure with a complex graph and trace why the method cannot find a path; done means identifying the cause and establishing the expected behavior for this case.
