Does anybody know why I'm not properly getting passes form my roommate anymore? For the first several months I had my 3DS I've been getting at least one street pass from my roommate a day, sometimes two or three depending on how long we're both home during the day. That meant once or twice a day I was able to run his Mii through the different games like Puzzle Swap, Find Mii and Flower Town. But for the last month or two, I'm not getting his Mii in my Plaza. The light will glow green, and I'll have a notice about his house's info being updated for Animal Crossing New Leaf, but his Mii won't show up in my plaza so I can play the games. It's making it near impossible to get anywhere in Flower Town and Monster Manor since I don't usually pass anybody when I'm heading to and from work.
I don't understand why I've suddenly stopped getting passes from him. Is there just a limit to how many times you can tag one person? I know I'm at around 150 or so passes with him since I first got my 3DS.
