New issue for me. Put together a Big Boy excursion consist and added 2 aux tenders from DSGDDR. There doesn't appear to be any other requirements and appear to be self contained. I open the editor and place them, F2, then click the orange arrow. They are now missing from the consist except for the couplers. If I go back into the editor they are still missing. What am I missing here. I have deleted the file for these and installed a fresh copy.
Here is the link if anyone wants to check the file structure.
