When I couple the wagons it does not change to the next text. I last played this route few years ago and it was still like that.
Unlikely to get fixed at this point. Even if the original developer still has an interest in the route and can fix the scenario, would need to go through DTG to get published and we don’t really know how the land lies with, to them, minor support issues for TSC DLC.
Torfmeister did a lot of coupler fixes (in RWA library) as many coupling issues are caused by incorrect distances, worth a try? Here's a link to the RWA file: https://railworksamerica.com/index....156:tmcouplerfix&catid=23:miscellaneous-files
This message was quite timely, as I was just about to run the same scenario. I applied the patch for GP40 & Granger, and was able to complete all tasks successfully. Thanks for the helpful advice! One downside was that my score was 0 (and I did not gain any experience points) even though no points were deducted while playing the scenario (the HUD showed 1000 and the game summary showed no errors). Has anyone achieved a positive score?
