Was fooling around with widescreen fixes and noticed this. Somehow, when ANY fix is applied to the GOG version, the placard you're supposed to pick up in the area where Cynthia's belongings are erroneously becomes the "Watchfulness Placard", no prompt is given to pick it up, and the game freezes.
Removed the widescreen fix and came to this point in the vanilla GOG version and it works as intended: you are given a prompt to pick up the placard, and it is the "Temptation Placard", the correct placard for Cynthia.
Not sure how the widescreen fixes are able to manipulate code like this, but a fix is appreciated.
