They may just be super small changes you're not used to yet or you're getting unlucky. Things like light switches duplicating, some of the objects in the bedroom changing direction can be hard to notice if you're not familiar yet. Some things to keep in mind, if the camera goes out in a room you're looking at, something has changed in that room. If you're really not finding anything try reporting displacement or mimic in some of the rooms with clutter like the bedroom or the basement. Hope this helps!
