hey, I have seen many times in technologies descriptions "reveals [resource]", for example automobiles, but later on many of these resources are nowhere on map. My English dictionary shows that "reveal" means something like discover, and for example, when got industrialism then bauxite ore was discovered, but it didnt happen with many other resources. Also, my computer crashed when i tried to put "replicators" on map using world builder. I am doing something wrong?
