Hi,
I've started playing X-Wing only recently. I am using Squad Builder to build potential squads and then I purchase miniatures. In theory, the builder should not allow me to select items that are not in my collection. I bought Y-Wing today and it seems that the app offers upgrade choices that are not available in the expansions. In this case for example I can select Han Solo as a gunner in the app, however, the expansion had only Agile Gunner. I assume it's the app that is bugged rather than the expansion is missing cards?
