I may be missing something here, but I can't work out how to start the vulcanus tech tree. It says that in order to get a foundry I need to craft some Tungsten Carbide. In order to mine tungsten I need a big mining drill, but in order to unlock the big mining drill I need to craft a Foundry. But I can't even research Foundry until I have a big mining drill, so this just fundamentally doesn't work.
Any explanation as to how this should be approached? Have I got a bugged install?
