So, this game is super frustrating. I've had the game for months now, and had StreetPass enabled since day 1, and have never gotten a single tag. Now that I have two 3DSes - one fully updated and one on 4.5, I thought I'd do a little test. I took the game card and put it in my freshly formatted 4.5 3DS, enabled StreetPass and placed a gift to be distributed over StreetPass. Closed both systems, nothing. I even tried placing *two* gifts (as in, one from another level), quitting the level and exiting the game and it STILL won't transmit anything. This is incredibly annoying, as I just want to figure out how to use StreetPass on this game! Do game cards have some sort of serial/ID that would tell it "oh, this dude's using the same game card on two systems, so don't do anything"? Because otherwise I just don't get what's wrong!
