The step in question is this:
Let's get one for ourselves!
Advance on the military track. The next space is in tier 2, so we'll need to pay 2 resources! Pay with a star and a coin.
That is when the tutorial wants me to advance to STANDING ARMY/4, which costs one culture and one other resource. When I first select to pay with culture, the tutorial throws a "This move is not authorized now" message at me. When I try to pay the coin first, I get the same message. It was a very good tutorial up to that point. Am I doing something wrong or is the tutorial broken? I don't see how I can select two resources at once, the selection only moves between the resources.
