You mean that you can't find where the treasure is hidden? Did you start counting from the precise spot you see with the telescope? If you hit any of the checkpoints in the wrong order, you have to start from the beginning. I have added a screenshot of the starting point to the walkthrough, for reference.
Edit: Checking the code, it's possible to mess the steps recognition by walking on the starting point twice in a row, however walking back to it and trying again should fix the issue, so if that's the problem simply trying again should be a natural workaround (this will be fixed from version 0.9.20 onward).
