Invisible A.I., squad disappearing; cannot launch game for blank screen - XBOX ?

Question

Playing F.N.B.F. till the early hours of the morning as you do...; cycled through some form of breakthrough, maybe a couple of times; last game, the majority of the A.I. inc. single squad mate were not visible beyond coloured markers; end of game; squad appeared as a "D-pad" symbol; now locked in starting that next game with the prelude music, totally blank screen, as is the case trying to launch game, now; takes it right back there ?

Was after recent patch, but the game was working fine for hours; only me and another guy for the most part so was a bit unrealistic statistically, double XP; but still not ridiculous ?.

Q. What does one do to get the game working again ?

For anybody interested, was remedied by: Settings > System > Storage Devices > Clear local saved games.

Personally, I'm not really bothered about how those online happenings can corrupt local files, since the most recent patch but here is screen grabs; only other strange experiences, historically is A.I. present with no hit boxes (Also lots of noobs, with an overpowered 'prototype' gun which seems to be all the rage, recently (?).
