Hmmm I have the same problem, but all the above mentioned things don't help me. Just for the record, I have to put all 4 ingredients on the floor inside the circle euh? Including the runestone euh? And then talk to the instructor?
I tried different approaches, picked up the items, went outside room , saved and loaded again, but nothing works, i'm completely stuck.
Furthermore I tried to implement the latest patch (had 1.44) hoping that would solve the issue, but that didn't work either, even more, one of the imps has now dissapeared in an area that is impossible to reach, so I can forget the drug-quest as well......
Besides, I talked to that lotharhar, but the imp(s) doesn't give me the key by means of any question i can ask them. There is no conversation at all about keys, so its also impossible for me to get the key from the door. I remember there was a conversation about the key in the beginning, and that he didn't want to give it to me, now he doesn't even talk about it, only that he saw me in his dreams pffffffffffffffffff
Any suggestions?
