Yet Another Bug!
On A4 you need to find a book for the 2nd summoning quest. nixfix lets you go down to the 2nd pipes level and on dead imp i've found the book, which also marked the drugs quest as done. I also killed the big monster Nixfix referred to and my questlog tells me I should tell him.
HOWEVER, nixfix only has option to talk about things BEFORE the book quest.
There's not an option to talk about teh slain monster and all drugs related
topics still seem to think the case isn't solved. The quest enrty for Nixfix also remains...
