When i mine urainium ore with the correct drill, structures requiring it don't unlock. Do I need to smelt it or am I just a potato?
Maybe because it glitched?
If you don't have the answer yet, then I'll tell you. There are no structures that require uranium to build; uranium is used for ammo or for making energy. Instead, the green bar you see when building structures is dirium; to get dirium, you need to build a crucible, which I think you need titanium and steel for (the game should tell you what it requires). Then you can build stuff requiring it. Hope this answers your question!
uranium isnt even in the game ;-
