I usually play GTA V at home with my Ethernet cable connected and my 16 GB USB stick to save progress. So far, I've gained 20% completion.
But I'm at a friends house with the same Xbox, and we can't connect it to internet. When we tried to play, we had to start the game over with Mission 1 "Prologue" and for some reason we cant save progress on the USB stick. I think this is because the game requires internet in order to save.
Unfortunately this means each time we start up the Xbox we have to start over.
Is there any workaround or solution to this?
