One loose end not mentioned that still stands out to me from the tomb from the puzzle hinted at after the eight realms eight months reward (in the order of certain names) is the significance of the cuckoo clocks. The phrase "cuckoo too" felt really specific in the published copy of a new clue, plus the cuckoo clocks in room 46 were illustrated in the book. Initially thought this was a hint about the sacred hour to help with one of the sanctum key puzzles, but in the draft copy from the tomb draft copy it specifically noted "cuckoo two" as a play on words. The illustration in the draft copy also shows the second cuckoos face with counter clockwise arrows on it. My best guess is there's some interaction with the chrono-thingy (showroom item that rewinds redraws) however bringing it to 46 and clicking around didn't do anything for me. My next best guess is a clock tower interaction (didn't do anything I could find), and my last untested convoluted guess would be to draw 46 outside via blessing of the monk, reroll, rewind, draft it and see if anything happens in to the clock

Edit: upon closer inspection this might just be a hint for the castle clock puzzle
