It seems to be that everyone is receiving the same thing in the advent gifts unless your farm is not at the level for that particular feature yet.

For eg, the day that I got the Rose booster my daughter, who's farm hasn't reached the level where you can access boosters yet, got 2 duct tapes instead.

And now, with the puzzle pieces, everyone who has the sanctuary is getting them & those who haven't opened the sanctuary yet are receiving something else, depending on level, as an alternative.

Rather 'puzzling' 😉 though is farmers getting the PP when they already have all the (currently) available sanctuary animals. With that happening, along with the hidden sign in the sneak peek picture, the predictions that we may be getting new animals might have some credence.

Or, it could be as simple as some gifts being more useful to some than others. Who knows?! (Answer: SC)
