page 4 of the Avalon Hill/Hasbro 2021 KK Quest book version lists the contents and under "Cardboard sheet includes:" it lists every tile including the new STATUE TILE but strangely shows it beneath the Giant Stone Boulder...
I will peruse the quest books and rulebooks to see if any mention is made whatsoever of the new tiles included in KK and ROTWL, or if they have no game application beyond scenery for the blank quest map to create your own.
The STATUE tILE is not on any of the quest maps that I could see in the 2021 quest book, and it has no description anywhere in the text. On the blank map and tile legend page 31 it is shown with no description.
