the servers allocate people into high ping region, like asia, u should be allocated in HK or japan etc, but it allocate u into austraila , if the servers overload( it's possible, as it originally is enough for these region players only), so if all asia players is allocated into austraila regions only, it must overlaod. it happen before, a week ago. so it can be fixed from ubisfot , or offcial, u can't do anything like verification, or reinstall the game. so take a break ..... as u can't change region in that time even it have the choice in the menu. as the server side can't do that when this "bug" happen,

u get into a overload server, so it will crash
