Anyone else run into this? Am I a terribly silly person who is missing something hilariously obvious? It’s the only thing blocking me from completing the achievement.
You and me both, Arrakiv. That isn’t the cloud we are looking for. N°6 is more to the end of zone 2. It’s a sidetrack and it has a flower to jump onto the giant cloud formation (the one where you kill the last Assassins for the achievement). Cloud 6 will be unlocked as soon as you take that jump with the flower
