Okay so last night I saw that my little sister had the aqours downloading screen from love live on the iPad she uses. She was kinda hiding it, and knowing her she obviously tried to download the game without asking anyone about it. I checked the game on the iPad I use and it just shows this:

I guess just downloading it onto another device and the fact that they use the same Game Center account made the data transfer. the iPad my sister uses didn't have enough room to download it. My parents just deleted the game on her iPad hoping the data would go back to mine, but it still hasn't. They contacted the love live support, and I guess they couldn't do anything but I don't know because I haven't read their response my parents just told me about it. I need to know how to get the data from all my progress into the iPad I use. If you know how to fix this please do tell me because I had like over 620 love gems to scout for pirate rin . . .
