So anyway, I need to advance in the DLC, however sleep deprived me, for some completely not thought out reason I can't even recall, decided he would reset the quest River Monsters, now I can have it given to me again and using the console to make it completed isn't cutting it.

Is there a way to re-give my self the quest or just force Walking Cloud to start The Trecherous Road?

Never mind about that, I fixed it just by loading a previous save I forgot I had.

Now how do I plant mining explosives?

^{there will be an outline of the charges in the cave where your supposed to plant them.}

The mining explosive outline can be very difficult to see on the ground because it blends in with the surroundings. It may take you a while to find them even with the markers.
