Yes - she is. She has had no problem navigating any of the worlds until now. We have upgraded to the V2.0 latest update. Is there something in a previous world that she was supposed to do? She hasn't gotten the black button built either.
The game action is - she hits the info block with the golden wrench. It crumbles then reappears. The same happens with the other info block near the big "building" with the TNT cubes. When she also hits the floor of the blue platform and they crumble and then reappear.
