I'm thinking about it from the creator's point of view. I would not put out another puzzle that follows the same rules. I would want the new challenge to be fresh and have new twists and turns.

We all be waiting for new puzzle, sure. If creator will not create the puzzle, I will decide myself to publish the solution or not depending of situation. At this time puzzle is solved, solution is known and nothing points that detailed solution is required for community.
And I think differently ... I think it is a simple element of closing the topic of this shaft. The left was removed from the wallet by the owner, and NO WAY to solve the solution does not exist and never existed, because the solution is just the same as the answer - only this connects them ... and as the second shaft is not and will not be - in public the topic is closed without information on how this could be resolved. Noble, smart and coarse ... like a question, a hint, an answer and a non-existent solution. Over and out
