I've been trying to complete this achievement for a while now, and I've followed the wiki, YouTube videos etc., however most of the information is over 3-8 years old.
The route used to get to Golden Badge 4 is blocked. is there something I'm missing?
Right after the first checkpoint for the Retrospective Runaround JP there should be a hole in the ground that leads to the path, but the ground is solid and no alternate route.
please help. .
