While perusing solutions to wasteland explorers crashing the game I noticed a comment claiming the mysterious stranger stole lunchboxes. I paid no heed to this as it sounded unfair. Lo and behold I am down to zero lunchboxes after previously possessing nine (four saved up and five from the latest update). Granted, I have yet to see a single mysterious stranger, but my vault is fairly large and I seldom zoom in to rooms. Whatever the reason, I see no reason to ever purchase lunchboxes again if they can abscond with no notice.
