Hi, I'm in need of help.

I'm in act 3 and I just can't save Anais. After talking to Roche inside the sewers, the screen fades to black, the sound of mission being updated triggers, but the black screen don't go away. I can walk, attack, but can't see anything and can't continue the game.

What can I do? Please help :(

Its a guess , try lowering your texture memory size in the options and see if that helps.
Then turn it back up afterward if it does.

I don't recall exactly, but there may be an Auto Save point there that is kinda loopy. Might need to load earlier and make sure you don't linger in the wrong spot in the sewer.

Even if I am remembering poorly, you may just be able to load an earlier save and get through that bit without a glitch. (Restart the game first, too.)
