When we play multiplayer ipad mini vs ipad mini 2 99% of the time he will see what you see in the attachment, seems the data is not loading on the ipad mini.
Also he will not be able to see me but if he closes the app and launches it again he's ok for a few minutes.
I've reinstalled the game same issue, even playing online we get the same problem
I don't have that issue on my ipad mini 2.
