Just found the answer. One is Fall 2x3 bare tree2 and the other is Fall 2x3 bare tree. They use a few different tree colors and arrangments. Will add detail when I can :)

Hi, that's what I wondered, too. Since it's for something special, I'm going to leave up both just to make sure. I'll have to figure it out later.
I am pretty sure that they are two different files, though, since I am not getting a duplicate prefab asset name error.
These were made in a rush, as you can see from the page here lol ^ Still, they make decorating so much faster.

Did this get published twice?
