Hi there, An issue I have come across.
-Turn on Xbox
-Sign into Profile from Dashboard
-Boot up Forza 7
-Game loads the Turn 10 Introduction Video
-Forza 7 then shows the Loading screen with the Porsche and the Driver Standing there
-Xbox then turns off - completely off, have to physically restart it
Tried this several times in this order and same thing except one time it crashed out on the Turn 10 intro Video
Work around, have found not signing in on the Dashboard and just loading the game after booting the Xbox works, you just have to sign in when Forza 7 asks after the loading screens.
Just a heads up for the Devs and Community
