I am in the water in the room with af statue down below in the center of the pool. I think I'm supposed to pull the lever at the end of the tunnel in the water. But I can't. Nothing happens.
 Have you had the same problem? How did you solve it?
  
 
  
  
    I have solved my problem myself.
 I started the level all over again. It takes no time when you know what to do.
 I did exactly the same things, but this time I was able to pull the lever.
 It must have been what you professional guys call a bug?
