I'm having an issue with multiple AP scenarios because the following is missing: Anyone knows where this is coming from?
The game work by looking for files in specific locations - if they are not in the location it expects it gives an error message If you read what is says on the highlighted line - RSC\Class66Pack03 is where the wagons come from. https://store.steampowered.com/app/222568/Train_Simulator_EWS_Class_66_v20_Loco_AddOn/ I have no idea if the Stand Alone wagons suggested above would install to the same location. If they don't the game would not see them and report them as missing Also AP normally give a list of what extra DLC is required to run their scenarios
I found it at the end: this particular wagon comes with the AP Class 56 Extra Stock. Both the above I had. Was painful, but sorted.
