Zonathrope: well unless gog does something about it, I'll be requesting a refund.
Even if this was a case with the PC original this IS a gamebreaking bug and should not have been shipped in such a condition.
Sexy.KOT69: It's not a bug, I believe it is a design decision. I think they released a PC version first, updated it and released a PS1 version afterwards.
You are absolutely right. It was commonly known at the time, which is why many (like myself) moved from the PC version to the PS1 game. Whether anyone will ever release a patch for it is anyone's guess. We still live in hpoe.
I don't think GOG should remove it, but they might consider adding a note to the listing to explain the difference for those that aren't aware of it.
