Do you change the tires, take it for a short drive, then torque them? Are they alloy rims? Torqued to 80 ft lbs, and is your torque wrench accurate?
Once you get a tiny bit of movement, it is very possible for all of them to be loose like that. I've seen it before. It's possible you did everything right and the lug broke form fatigue, then the others loosened, but if the others were torqued properly I don't see that as entirely likely.
