I'm on the wharfs where you have to turn on the lighthouses on to get the boats to move. [spoiler=]It's just before Umah dies. [/spoiler]This is the part where you give the password to the guard, who lets you through the gate. To the left, there is a switch to open a gate, which closes behind you. You are now on a dock with a light house on it and you need to use your telekinesis to turn on the lighthouse. When the boat leaves... THERE'S NOTHING THERE!!! There's only water. I've gotten past this point once but my stupid brother turned off the game before I could save. Now I can't get back. PLEASE HELP!!!!

In my experience, the game is a little buggy that way. Unfortunately, there's not really much you can do, as far as I know, aside from starting over and cascading your saves.
