Up where the campfire is at is a small box somewhere on the construction site, which you need to push down and over to the wrench then you can climb up and get it, its a little finnicky but not impossible. (Im going of my memory with this sorry if it turns out to be wrong)
Oh thx!! I managed it yesterday, you're half right lol. There's a cave enterance below construction site cliff. it's hidden behind trees. you go inside, campfire's burning lol. And outside, you can go to cliff where small box is located!
