Wondering if anyone else is experiencing this issue.

I just bought and installed the game yesterday (PS3) and after waiting for the 2.4gb update to download and install managed to log on without much trouble. I was able to log out and back in throughout the night without any problems, but this morning when I launched, PSN downloaded a little 9mb update and now I've gone to log back in to discover I'm once again downloading the entire 2.4gb update.

Is this an error and if so is there any way around it? I seriously would hate to have to do this for every patch.
