Just had my first online race with the new patch. This is what happened :

Raced one other guy on Chenghou P. fwd, and he was sitting at the mouth of the tunnel the entire race, and he won!
I then quit to the lobby, but I was still hosting apparently, and when I tried joining my own race my PS3 froze...
And this was the FIRST time I played with the patch. So, basically - three errors in the first five minutes of the new patch...
