Missing diary note (trapped)

[Margaret]

Thanks, but the problem was that the note I got in that room was the previous note (the one that talks about the rock collapsing). I still don't know what went wrong, but I started the game over from the start, and this time it worked. I think I missed finding a note earlier on, and that messed up the sequence.
Anyway, all good now; thanks for replying so quickly.
