I'd love for this to work, but it doesn't. Any time my party is brought back into the area map after going through the crystal destruction sequence, the conversation with the Eyeless never starts, and the game journal wants me to redo the sequence all over again. I've even tried redoing the entire area from start to finish with these edits, and as soon as I would expect the Eyeless conversation to start, nothing happens.
Anyone run into this issue as well?
EDIT - Doesn't work using "And" or "Or", either.
