Well, even if I can't rule it out - this is the first time I hear about this issue. What exact message do you see when you check the place in which naphthalene pills are?
Down in this message list, there's also a complete video walkthrough - if you don't mind you could check it to see if there's something different. Anyway - sorry for that
Looking at the walkthrough, when the user clicks on the 'jar full of pills' for the second time, I noticed that they got a different line saying: "It's a big jar filled with whitish pills... they look similar to something else I've already seen.", in which I don't get so I assumed you edited the dialogue and I went straight to room 117 to collect the naphthalene pills.
Again, the user gets the additional line: "These pills are oddly similar enough to Rohypnol ones. Let's take them." where they can retrieve it while I cannot do any of this. It seems I am unable to progress in the game.
Overall, no worries! I have enjoyed the game so far. Keep it up!
