Hmm, it's possible. Though I thought I fixed that bug way back. So you can't enter Marburys room anymore? You should get the crowbar when you look at the arm on his desk (from memory).

Yeah, it wouldn't let me through the door. Originally I had entered the professors office and spoke with him but didn't click on anything. It's been a week so the details are hazy but I remember not wanting to advance yet so I left his office. After leaving the hallway to a different room and coming back to the hallway the "Oh I know him, he murdered me." event triggered. If there's a way I can give you an event log let me know. I really want to finish it, but I'm gonna wait a bit so I don't just click through the dialogue trying to get back to where I was, instead I'd like to experience it fully again to give it a fair chance. I love your style and I miss these kinds of games. Thanks for the great hours, the laughs, and reliving my childhood.
