I really, really hate spending points on the wrong Tech for what I want to do. So I would have liked to see here and in the Guide the
requirements for Puzzle 9, which only hint at the exact method, that I found on another site:
A Master Builder, a Chief, and Levels 3 in both Restoration and Leadership.
(BtW: I don't figure mentioning the statue is any kind of spoiler. That's got to be about as explicit as any silhouette symbol for the 48 VV Puzzles so far.)
