Hi Federico! I noticed a bug in the game. According to the map of the game, to the west of the dining hall you should find the kitchen, however the text that appears is for the vegetable pantry. Also, if you try to look at the stains, that you are supposed to see in the pantry, the game says that you don't see any, whereas if you tell it to look at the kitchen, the command works. This screenshot explains it better:
