I see an interesting point in the dunes later in this stage. They are following part of stage 3 in reverse, but then the stage 8 WPC point is slightly beyond where the tracks from stage 3 will be. Some may see all the tracks "turning to the left" and follow them instead of going 500 meters further to the WPC. The leaders shouldn't fall for that because they know the tracks they see are from an earlier day, but those further back may make this mistake.
A WPM has an 800 meter unmasking radius (when the arrow pops up), and a 200 meter validation radius. But a WPC has no unmasking radius (no arrow, ever), and a 300 meter validation radius. So, they will not get an arrow as they approach that WPC, which will make it much more difficult to find the point, especially when there are old tracks going the wrong way just before that point. To me this looks like a planned navigation challenge by ASO.
