Dam nice little big update.
I had problems with that as well.
I'll play Multiplayer before I start the game without my Shep's face, and I hate Multiplayer.
I believe they updated the character models and rendering from ME2 (Me3 uses the updated ME2 PS3 engine I believe), so that explains the slight differences between faces.
I'm hoping it'll work okay with mine tomorrow. I might start from scratch anyway... my Shep always had a weird-ass upper lip which I didn't notice during the creation, but could never fix after that.
I did this update also, didnt see much difference as the quest itself appeared without any problems before i did the update.
What happend though is that it reloads the original coalesced.bin, so anyone that altered the coalesced.bin should make sure they have a copy of their altered coalesced.bin before doing this update, to be sure they still have their modded coalesced.
