I'm thinking I hit a glitch. I thought I did all of the puzzles but I don't have a music box note in my inventory as Stephen had and I cannot go back into the professor's room as I can no longer get the key. I do have some other key in inventory that I picked up somewhere (don't remember where) and it is not the key to my room (that one is in there also. So, I have my key, this other key, the puzzle box (puzzle finished), map, matches, sandpaper, axe, wine.
I finished the scavenger hunt, fish match on boathouse door, piano, masks, Japanese cards, garden puzzles, jigsaw puzzle, spot the difference, esp test, lotus flower, been in the doctor's and professor's rooms and gave the oil and map to the hag.
I don't really know if I did a music box puzzle while in the professor's room. I have seen the clues in the breakfast room (they still show up if I go in there). I also don't think I did a Totem Puzzle but don't see anything to do with it. Hints refer to the attic which has no further hot spots.
What am I missing or have I hit a glitch?
Thanks for your help.
