What you describe sounds like "semi-fogged" (you see the cost, but not the reward). This gets worse, if you have two or more visibility advancements. How to figure out what you might find on this territory? Is it a recipe, or perhaps a mine?Here is a picture on my current level. As you see the region is "semi-fogged". All we see is the army cost, and a recipe icon on map. We also see some mines in "semi-fogged" territories. Here we won't know the name of the mine until it is completely visible, same as we won't see exactly what recipe is there. But it is clear if it is a mine, or a recipe.
