Guys, I just got an idea.

Since I bought the SSD for my PS3 few weeks ago, I made a backup of my ps3 data in order to restore it on the SSD.
I am sure I deleted the game data (4gb) before backup, but I am not sure about patch data. So if I kept it, than I have a chance to play 1.1 once again.

So I am about to backup my saves to the USB flash, restore from backup, restore saves and play without magic resistance and weird dragon bugs.

P.S.: I guess 1.2 saves wouldn't work with 1.1, so I just start a new warrior char\continue my archer which I didn't play on 1.2.
