Hi,
I solved all the puzzles except the last one but I need some help.
After opening the entrance to the secret city I have placed the sun dial on the left-hand side, seen the ghosts appear and have dropped a villager on them several times and revealed their story each time. However doing this dosn't seem to complete the puzzle and it still sais on the screen that the milestone has not yet been completed. What else do I need to do to complete it?
Can anyone please help me with this?

Please see this post.
