I've been playing 7 days for awhile now and I love it. Recently I've been playing with one friend on my boyfriends Xbox and I can always connect to my buddy on my boyfriends Xbox. A couple days ago I was home and using my Xbox and I was not able to play on that friends world. I went back to my boyfriends and I was able to play on my friends world again. I'm on the same profile for both my Xbox and my boyfriends Xbox. It seems like the Xbox that I first joined the world with is the only Xbox that I can join with. Thank you for your help
