Yeah, I'm aware, we ran out of time a bit with this. We never meant there should be only one way to solve a puzzle, but I figured that often the simplest ways need to be blocked to make it more challenging. The few barriers there were to placement, in the last puzzle, were a last minute addition. The random spot clicking is a bug, due to an earlier mechanic we had. Even so, you'll always have enough magnets, and if you have one extra, it's still solvable :)
