We are working on deploying a gas UN in a FGDB and are running into some weird behavior when running the Update Subnetwork tool. For some reason, any feature that is appended or copied over from our non-Utility Network dataset will not have the subnetwork attribute updated past the first intersecting pipe. Alternatively, when we manually digitize the new features, the subnetwork will populate past the first intersecting pipe. Not sure what is going on, but any input would be appreciated!
