Aye congrats! Later in the night tends to include anomalies that are either harder to spot or more rewarding to find.
A few people have mentioned the growth and shrink anomalies and I also found some of them a little hard to notice. It's difficult to find a middle ground because they're either not noticeable enough or too obvious with a tiny window where it's the perfect size change. But even then it's subjective to everyone.
Once you know how the size relates to other parts of the room, they're easy to spot like comparing anything else. With that being said, I will probably go in and resize some of the more troubling ones.
