I've played through the game and probably saved there a couple times but as it only happens in certain parts of the city I guess I might have just gotten lucky.

They're meant to be coming up with a fix that you can download if you have an early copy of the game and it's meant to have been fixed for future releases of it. Wish I could get a link but I'm on IE and it doesn't like having multiple tabs open.
I read about this too, but not all hope is lost as there is a non-update related fix for it. If you go to youtube, just look to the top comments on how others resolved the issue. Granted, it is a nasty little bug but can easily be avoided.
