I keep sending Johanna the Chrome Cargo train set. Wood, Bricks, glass nails. It never shows up as one sent? Do you know what I am doing wrong? thanks
pixel_player818276685 possibly not fulfilling the requirements of a set? https://forum.pixelfederation.com/trainstation/d/39528-what-is-a-full-set
chrome cargo requires 6 wagons http://trainstation.wikia.com/wiki/Chrome_Cargo_I
also a little tip - there is always a non-gem option available to complete contracts/achievements and with the chrome cargo the wood and brick wagons aren't necessary, a mixture of glass and nails totalling 6 wagons should count
