When i finish any of the tutorials, i hear "structure complete" when there is no structure "going-to-be-completed"!
Also, in Basic Logistics tutorial, the game tells you to "select the construction frigate and build 2 Military labs". If you do so, it works. Whatever, if instead of selecting the construction frigate you choose to construct those labs while by the planet buttons, the tutorial doesn´t continue.
Thats all folks!
