Apple Game Frameworks and Technologies: Dungeon tiles not "there" for Scenes 2 & 3

Title: Apple Game Frameworks and Technologies: Dungeon tiles not “there” for Scenes 2 & 3 (page 361)

When I copy over GameScene_2.sks, and GameScene_3.sks into my project, the dungeon tiles are not showing up (and are constraint Val’s movement if I try to play those levels)

I’ll attempt to see if I can determine how to fix it, but I would think you’d want them to “just work”.

(Using Xcode 12, btw)
