Why do I see message "the world fades" on The Dusty Path?

Solution 1:

You probably ran out of cured meat.

If you notice, when you move on the map, you actually consume meat every few steps. If you run out of steps, starvation will "set in". Then, the world will fade as you die from starvation. If you have a trading post, eventually you can buy a wagon which lets you carry more on adventures.
