On the Subject of Jumbled Buttons

These unpaid apprentices, man. Always getting their wires crossed.

See Appendix of Directing Buttons for identifying modules in the _ Buttons family.

This module presents a 4×4 grid of buttons, each coloured orange, lime, cyan or pink. These buttons represent a path taken through the grid, so that every square within it has been visited exactly once after 15 moves (where orange means a movement up, lime means a movement to the right, cyan means a movement down and pink means a movement left).

...At least, they used to form a path, until someone messed up the internals of the module, swapping two of the buttons on the module and ruining the intended path. Great.

To solve the module, first swap two different buttons (you cannot swap two of the same color) to form the aforementioned path. Then, press the button that is the starting point of the new path.

The module will only strike once you enter a starting location that is not the start of a path traversing the entire button grid.
