I've tried to play it twice. Both times I was unable to get the Light Step as there was no hot spot on it. The first time, in my attempts to get it, I accidentally triggered the door to the ship again and the camera got stuck in the view of the ship from the outside and stopped tracking the protagonist. In the second time I played it, I made sure to avoid that, but still couldn't get the Light Step. Took a long time to get around, but couldn't really find anything after finding the map markers and reporting back to the mayor, so I gave up :(
