In QD the rebuilt Bulleid Light Pacific comes with 3 & 6 Maunsell coach consists as standard, I created a 9 car Maunsell consists and the 3 & 6 coach consists disappeared.
Unless you gave your consist information the Exact same details then it would put your consist in a different folder. I created a QD Consist for a Class 86 but because some of the base info was slightly different it's display name is different but it's still there Peter
