pick destroys rocks either. I thought about that place in the long passage where rocks look they block a passage into a side room, but those rocks won't get smashed.
I opened up the mission with TTLL, and I think I have all the nuggets I can see there:
- five in the secret
- one you can reach in a hole while hanging from vine going down to where the secret is
- one on the rim of the descent hole (the one you describe)
- one close by, in the passage, by skeletal remains
- four near the base of the mega vine by the start (three on ground level, one a bit higher up). One of the four is a bit into the long passage.
BTW, the nuggets are named "SN01" to "SN13", but there is no SN02.
