Hello, it seems that after the cat runs away when I approach it near the waterfall, I cannot advance any further. I talked to everybody time and time again, however there is one door that is closed and there is no way of opening it. I don't know if I misunderstood something or if there is a problem in the game.
EDIT: It looks you need to do things in a specific order otherwise you'll get stuck. If you talk to the lady about dimitri first, you won't be able to talk to her about the dog.
