In my quest book I have a notation saying I should go and tell the old imp (Nixfix, I think) about the monster I killed. I did kill a monster hiding in a well, but when I go back to talk to him (I have done this numerous times) he doesn't say anything about it.
I'm playing from a previous save in order to get BF3 key, but I know in a later save he did acknowledge that I killed the monster.
Did I break something? Can I continue on without his acknowledgement?
