Alright, so I went into Lyssak's spire, and killed one of the versions of him. I saw the conversation between the remaining two about his death. Then, a few turns later, I kill both remaining Lyssaks at the same time with an AOE spell. I get the little conversation window that I should see when killing the second one, but after that, nothing. No acknowledgment that I just killed Lyssak. I go back to town and try to talk to the mayor, but it appears that no one knows that I killed him. So my question is, is there a file I can edit to give me the necessary trigger to complete this quest? Otherwise, I'm fairly screwed.
