Hi,
I am working in Open roads and using drainage & utilities for a project. There was an issue of "loop in the network" while working in GVF rational flow and is resolved by using diversion network setup.
But now for lateral connection, though downstream conduit is set as diversion link and now having a new error as shown : "The upstream node of a diversion link must also have another connected downstream link".
It appears from your screen capture that you're trying to use a lateral connection in a way that it might not be able to handle. It looks like the upstream node for the lateral might have other conduits connected to it, in addition to the lateral?
