Missing cog?

[Bulbatron]

Again, thanks for getting back to me so quickly. I have re-entered the machine room a ton of times. In the end, when I couldn't find the cog anywhere I had no choice but to assume the final cog was hidden elsewhere, so I've been back and forth many times, so my first ever entry into the machine room is long gone.

Well having checked YouTube and the link you gave me, I'm pretty sure my game has indeed glitched.

I hate it when people accuse a game of being glitched just because they couldn't work out a puzzle, but I think I'm right on this occasion, though I'd be more than happy to be proven wrong.

So, one cog was in the room with the rod machine, lying on a small table. I actually remember finding that one, but I was a bit clumsy when picking it up and accidentally dropped it. I think it was at that point that it somehow glitched away.

I remember because I then found the one in the corridor outside and at first assumed it was the one from inside the room and I'd somehow thrown it into the corridor. But no, it's the actual one from the corridor.

The last one was in the room where you're supposed to insert the cogs, so it's this one and the one from the corridor that I now have.

I've been back and looked for the cog in the room with the rod machine, but there's no sign of it anywhere. I really don't know what else to do.

Is there anything else you can suggest or do? Or am I going to have to start again?
