publishing/paths issue with supporting files

I've run into this issue a few times with the v1.2 of the tools (running ArcGIS 10.4.1). I think it is isolated to arcgis server sites where the config-store and directories locations have been reconfigured to us a shared drive location such as a NAS file share. I have one system where the config-store and directories are local (C:\) and another system where they are in a shared location. This issue only seems to happen with the shared location configuration.

The issue is a failure to update the published path of the "ndsupportingfiles" folder in the serves. This causes failures with the routing tool and other solvers. Digging through the network traffic I've found an error where the services are trying to find the "defaulttravelmodes.json" file this path:

"original publishing location"\0\v101\ndsupportingfiles

rather than where they should be found in:

\\"sharedrivelocation"\arcgisserver\directories\arcgissystem\arcgisinput\Routing\NetworkAnalysis.GPServer\extracted\v101\ndsupportingfiles

If I replicate the exact path the service is looking for (path to original publication location) on the server and copy the ndsupportingfiles into that location, this repairs the issues with the services not functioning properly.

Start by reproducing the failure on ArcGIS 10.4.1 with the config-store and directories on a shared drive, then compare the published paths for the ndsupportingfiles folder. Done means services resolve defaulttravelmodes.json from the shared arcgisinput extracted path rather than the original publication location.
