Hi, all. Noob question here.

Just started playing CR on the iPad, and have encountered what I think is an anomaly. In two games now I've built Leonardo's Workshop, but my units don't upgrade when I reach the appropriate tech level, e.g., my riflemen don't become infantry when I discover mass production.

What am I missing?

Thanks in advance!
