[Bug thread] yeah, On my first try I found one.

4th chapter, a little beyond the wooden stairs that sets you off to the lighthouse there's a boat-house of sorts. With the house behind me and the "stone-driveway" in front of me. I wanted to walk down to the water, to find 2 stones. Where I was stuck. Forever.

During the end cutscene you can see "your shadow" as a bird. But there is no light source behind you to provide such a shadow. (I understand this was intentional but it still ain't right damnit! :P)
