Hmm, can you send me a picture of what the screen/dialog looks like directly before the error?

It didn't come up as an error just the DNA event triggered halfway through the femdom because it brings you back to the room and I assume the requirements were met for Maria's story to continue.
I'll see if I have an earlier save to send but likely I would need to replay the entire game.
but because it actually says this while in your room this happens
