Quoted from melumga:I know a couple of people here were having issues with the crane sensitivity. In my case, the crane was not registering hits on the 3 left-most positions. Turns out there was a split cable to the metal cage housing the pendulum (pictured below). The crane movement and the tight cable-ties were pinching it. Had to split it, strip it and twist it back together. Crane now registers every hit!
Good detective work!
