I got the game not so long ago but yet a few things I noticed:
-Recording via DVR doesn’t play ANY Audio, whether you have the Radio OFF or muted (also no car effects, essentially muted.)
-The 3.1GB TU which was Pushed broke the Announcer’s Voice (Ben) AND the GPS Voice.
-Barn Finds sometimes you see your character fade before the end of the cutscene (wasn’t present in the Xbox 360 Version?)
Some other things I noticed but aren’t too drastic:
-When the GPS voice worked, she would say take a left / right even if the turn was a right and left.
-AI sometimes drives off road and does circles on the grass (only present when free-roaming about (rare but hilarious)
-Head-To-Head races (only experienced with Bounty drivers) if you start and then do a rewind the AI forgets its course and drives straight or goes off-road even if there’s a brick wall (hilarious, again.)
Only thing I care about is:
-DVR not recording Audio
-GPS Voice Broke (Muted after 3.1GB update)
-Announcer Voice Broke (Muted after 3.1GB update)
