Hey, I looked up the script in the HPS file that were giving you the problem and I could not find anything wrong with the function that you said were the issue, although the only solution I might recommend that could work is if you try and get amnesia for steam instead of a torrent.
I'm guessing that the torrent version might get you the errors in some custom stories.
Hope this would be of any help! :)
