PS3 Witch Hunt Problem

Hi everyone. I finished this last DLC on PS3 but after the final choice, when I chose to follow Morrigan in the mirror, the game doesn't save the epilogue and so my choice...the game is 1.06 version, so the last version, and the DLC is downloaded from PSN. How can I solve? I d like to import my hero in DA2 also with the final choice you have to make in "Witch Hunt" DLC because I know it' s important in DA sequels and because I know it shuold autosave with the last patch.
