Hello, thanks for the quick reply. This was my first time installing the game, so I don't know why there are still glitches. Do I have to download the Mac version to get 1.2 or should the .exe one work too?
I think I know what's happening. You started Heather's quest with the comic book, then in the mean time, I suspect you started Seiko's quest, which will lock Heather's door. This is part of the path crossing bug fix. Heather's door will unlock once you've finished Seiko's story.
