Lizard's treasure and Country road are both still WIP since if you make some choice you can't end them.
The fact that he thought how to progress the war quest without Korg and not the country road quest makes me think he simply forgot about this possibility: I mean, Korg is cited only two times and at the end when he meets Ste for the first time, so he's not relevant to the story like in the orc's war.
