I found an error in the standard scenario "Challenger Working at Wycon" from the UP Challenger Loco Add-On. The number of the first car, from the first set of cars that you have to pick up, is duplicated. There is a second car in the Cheyenne Yard with the same number, therefor the game does not count the pick up as completed. It can be fixed easily in the editor, so I hope someone can take five minutes to fix this generally.
