Heya,
the disc is fine on position 0, but when it goes to position 1, it is slightly out and player 3 lights up instead of player 2. I can move the disc with my hand to get it to player 2, but I'm not sure how to adjust it so that the 'snow shoes' sit exactly on the contacts instead of in the middle.

Have attached three images. First image is when the disc is at position 0, second image is position 1 (you may be able to see the 'snow shoes' sitting in between the contacts) and the third image is position 1 from the other side.

Cheers!
Adam.
