I have 159 out of 160 gloden blocks. The last 1 is killing me. On this level,episode 4, chapter 1, "secret plans," there's a room you go into with a crane in it you can get into, 2 stormtroopers and 1 good guy are on a ledge across from you beyond a space you can fall , and there's a door on the other side c3po must open. The minikit detector arrow is right ontop of a ramp like thing (next to 4 tall cylinders bounty hunters can blow up)but I can't figure out how to make it appear. Last block of the game and I'm stumped. Please help , someone.
