Drill Parts Bug? (*spoiler*) -SOLVED-

[PuerNoctis]

Hello there,

(I am using the Steam version, fyi)

I am playing Amnesia at the moment (obviously), and I am quite stuck right now. But after reading through some walkthroughs I think I ran into some kind of bug...

To explain my current situation:

Currently I am standing in the morgue, I have assembled the syringe, and are trying to break the skull of the body. But to get into there, I thought I need the hand drill to make some kind of hole to extract the blood from - this was confirmed by the walkthroughs I read.

But I've never assembled the hand drill?! I only got two of the three parts at this point, and there is no possibility for me to get back into the storage area.

I still got the memento saying, that there was a cave-in and that I have to find another way into the storage area (explosives?), but I've never did this and came where I am now without it...

Here are two screenshots, for a better understanding:

(If the images are deleted, please tell me, I will re-upload them).

The first image shows my inventory with the TWO, unassembled drill parts and the syringe, and the second shows my memento log.

Can someone confirm that this is a bug, or is there just an optional way to break the skull?!

Any answers are very appreciated.

Cheers
