I was playing the premium module "Side Effects", and I had already given 2000 orens to Mr. Glover and decided to pay the interests instead of killing him. So I beat the third of the Band of Brethren (I defeated the other 2 before paying Glover) and went to Gunn's house as the quest said, but I couldn't find him there. I looked everywhere with no avail. Is there a way to make him reappear (assuming he isn't "hidden" somewhere)?
