Missions automatically initiating

I have a problem where if I try to log onto an Android device, like my wife's Samsung, It takes me to a different town altogether. My friends list is the same, but it takes me to a level 31 town, that only just built Burns Manor, and has a massive Brown House farm. I didn't touch anything, I just logged out, logged back in, and it was the same town again. So I just went back to my iPad, and got my own town back...
