Okay, so it looks like I got some kind of a bug. The patch note says:
Alice: Can be found at the FRONT DOOR on MONDAY MORNING!
Alice: Can be found in the GARDEN on WEDNESDAY AFTERNOON!
Alice: Can be found in the LIVING ROOM on FRIDAY MORNING!
But the thing is that I can talk to her in the garden and at the front door from Monday to Thursday anytime. So I go to the garden - she's there, go to the front door - she's also here. So she teleports like sans from undertale. But, starting from Friday I can only talk to Alice in the living room, when she is watching TV, and from Friday to Sunday that's the only way how I can interact with her.
