hey i thought the same thing was happening to me, but have you picked up the object on the kitchen table next to the cake? it's easy to miss & that seems to be what's stopping some people from progressing! ^-^
I tried to but it just says "[a few sweet treats left out for the guests]". I can't pick up anything. Thanks for trying though!
Edit: i figured it out. The kitchen is the door on the right in the room with a fireplace, not the place with the snacks. That door was so hidden T-T
