50% upgrade cost

[MinnesotaRuss]

I have the Professional Army upgrade in my government but I'm still being charged full price. What gives?

Are you talking about Strategic Resources or Gold? They were split up in the latest patch. In order to get 50% discount on Gold and Strategic resources, you need to slot Professional Army AND Retinues. They are combined with the Force Modernization card.
