I currently have 20+ settlement locations in my workshops list. There are a few sites that I decided simply weren't worth developing into full-blown settlements for one reason or another. (Limited space for housing and/or insufficient arable soil for growing crops primarily.) I had created a Supply network that had all of my active settlements connected. But somehow -- I haven't a clue how it happened -- the crucial link that connected the left-half of the network with the right-half of the network was redirected to one of those inactive settlement sites. So now all my active sites are getting by on only half of my available resources when I try to build anything.
Is there any way to terminate a route, short of tracking down the specific Provisioner to assign him to a different route? (Which is something that MUST be done in the settlement site which is the Provisioner's home base.) Just identifying which Provisioner is THE one I'm looking for is difficult because I have three routes that terminate at this location and another three that originate there -- and NONE of the Provisioners indicate what their route's end points are.
