Okay, I see what happened, you hadn't gone to talk to her after the ritual, so a variable got stuck. We hadn't considered that scenario, but it's good that you pointed it to us.
Replace this file in the game, so that, before she appears, it will unstuck that variable.
To do so, just: Scroll back and save your game right before she says "This is a mockery of our beliefs, right?" and close the game.
Open the game folder, and inside the "game" folder replace this file. Then, just open the game and load your saved file.
We are going to add a security measure so that this situation does not happen to anyone else. Thank you very much for the observation.
