Three Dollar Quill

I decided to keep focusing on sudoku hunt stuff today. I'm getting close to finishing, but I'm going to need to ask for help, since I don't think I've done a puzzle like Petra before, and I'm not sure where to start. Also, I'm curious what the intended solution path was for Machu Picchu, because what I did worked, and was not bifurcation, but it still felt icky.

Other stuff that's happening... The linting plugin I'm using seems to handle deleting text in normal mode really weirdly/poorly. Stuff persists way longer than it should.

Anyway, I'm going to take it easy: random other stuff after I publish this, and focus on Petra and finishing the hunt tomorrow.

Good night.
