Why the Pieces Really Fell
The checker pieces did not fall by accident. The interplanetary construction company was hired to deliver them. Checker Town was always the destination. The vessel was not lost. It was parked.
Current working theory: Checker Town was seeded. A game was started. Someone, somewhere, is still waiting to play their turn.
Note: The identity of who placed the order has been redacted from every known record. The order number still exists in the manifest. It has not been paid.
