Playing the tutorial we have a problem.
On the object to select mining as the technology being researched... well I didn't select it, I instead picked refined production. Clicked end turn twice. Mining was finished research, but the tutorial did not progress... It demands that I select mining technology to move on, but now I can't research this as I already did.
A fine punishment for those that don't listen, but probably something you don't want to do for beginner players.
