New Wipeout HD patch

[dreadofmondays]

Not sure, but it looks like these are caused by the patch:
Can confirm all three, happened tonight one by one:
Lobby screen got stuck with the buttons blanked out; I was unable to do anything, even quit; had to restart game. Other players reported the game was waiting for me during this time.
Came obviously second and third in three races, was told I was first for all of them (other player's screen said he was first)
Lost connection to the server during a tournament (god damn it sony) and was unable to reconnect. While I sat watching the 'connect...' screen, I was using PSN to chat and checking the forums. The problem wasn't with me.
Not good enough guys, clean up your act! -.-
Edit: further playing caused the network crash error five times, and the lobby freeze bug another once. I give up for tonight; I'll come back when Sony have learnt how to write a game, because the obviously know stuff-all right now.
