Missing item: Hollow needle at the end of the cellar

[Romulator]

Well, I'm not entirely sure about using the save file from the demo

Load up Amnesia and select Load Game instead of Continue. From there, load up the autosave file which puts you at the start of the map you're stuck at - it should be at the top of the list, or second, depending if you saved it afterwards. That should fix it.

If not, go back a map beforehand, rerun through that one, and then try to find the needle again.
