Hey guys, trying to do the quest biohazard and I'm up to the part where I need to get the touch paper from the chemist. I talk to the chemist and select the option "Talk about Biohazard..." and he simply replies with "Sorry, we're just about to close, you'll have to come back later" and then the dialogue box closes. I have all three vials on me, and have done the quest as instructed up to this point using the guide on runehq. Is there something else I may be missing? As I understand it the dialogue is supposed to continue after this point. Cheers in advance for the help
