"Trick or Treat" is the CL that I have begun the walkthrough process on ... trying to solve it, myself. I ran out of time in my first attempt, and had to leave it. But as a result of that first attempt, I will have a map for the first Crumble Bridge sub-puzzle ... I needed it for myself! My schedule for the next few dayz is such that it will likely be late Wednesday (or probably Thursday afternoon) before I have something to offer.
