Hi! after I passed the dinosaur room, I'm inside another room (the one where it's written "All hail the table"). Then in the library through the first door on the left side, I find a stone and a stick but there is no instruction on what I should do with them, so I wasn't able to continue because, in the second door, there is a stone which I can't break. Not sure if it's a bug or if I missed a clue.
