I am on the final contract for Ethan II. It is asking to send Legato train sets 3 times. When I click on the train set to see what is required to make up a Legato Train set, it says the engine has a power of 21 but the amount of cars that it shows to make up the set only add up to 19 in does not show the other two cars anywhere. Does anyone know if this is a glitch because I can’t find the other 2 anywhere. Thanks for your help
