This is a known issue that has been fixed. I posted a fix at the Hypnopics Collective and will update the update as such, but download the attached file, unzip and copy compiled.js into the folder Javascripts in your game installation
I currently face a bug, when I wait for catherine at the construction site and call her, she does say to turn around but nothing happens
The developer answers that query on this very page
If you don't want to download the fix, you can just keep calling her - it eventually worked for me.
@cmacleod42 - I'm afraid I need to blame you for not getting as much work done on my own game this weekend as I had planned. I tried ASFA about a year ago and didn't make it very far, got bored and stopped playing. I decided to stick with it this time round and whilst I would have loved to see video content rather than mostly the pictures, I must have played for about 12 hours over Saturday/Sunday.
I had the Catherine bug but other than that I don't think I came across any more, I did have trouble with some of the restrictions in the game such as timed events (I totally messed up the mom/gabby one in my first play) and I had trouble with Kate although I think it was just not knowing where she is and what actions to take when I find her - I do think there is a lot of room for her content to be expanded, specifically in between her intro and endgame, it feels a bit off that you study with her and then the next time she isn't under a spell you guys are in love. Would have really enjoyed a more fleshed out Room 101 scene, more text and interactions perhaps that revolve around a battle of charms to control Kate or some such.
Even just some extra text lines to flesh it out, such as..
Either way, there is a ton of content in the game and I think the level of response you show around here and the other forums (TFGS, Hypnopics) is really dedicated and patient. I look forward to seeing what comes next!
