I am posting each of my suggestions separately. I realise that makes a large number of posts, but it ensures that no suggestion gets lost if there are a lot of comments.
Suggestion 18: Currently, if you are in the hero window and you click on “Workshop” you will get an error message if you are not in your first city. The message states that you haven’t built the workshop yet. Since it is impossible to build a workshop in any city but the original city, this is annoying. Please allow us to go to the workshop no matter what city we may be in. If this requires you to switch us to the first city, so be it.
