I'm a save scummer, and noticed that for most things it works fine, but it failed on two occasions. Because one instance it failed turned out to be helpful, I doubt the dev intended it.
The first was when I found her key and saw the photos on the tablet. After a reload to a point before then, I was still able to talk to the cousin about the whiskey.
The second was shortly afterward when I got caught peeping on her in the shower. I reloaded, but was told that I already got caught once.
Also curious: There was absolutely nobody on Saturday, even though I am pretty sure Cousin said that her friend was coming Saturday. The scene where the friend showed up and took over the bedroom happened on Sunday morning.
Just fyi.
