It doesn't seem likely that a rogue customs agent happened to be a pinball fanatic who hatched a nefarious plan to pilfer a bunch of mods to sell on the black market. Is it possible that maybe the label got dislodged from the box and attached to another random box? I've had that happen before ordering something on eBay where the shipping label got stuck onto the wrong package and I ended up with some dude's knee brace. (didn't keep it... found the correct address and forwarded it on)
