No, for real, it’s in there. If you search ‘dragon’ in the art folder, you will see a dragon.dae file and a dragon.xml file. Then, in the Plane.xml file in the simulation folder, just change the actor to be the dragon, not the plane. Try it!
Oh, I never thought of hunting down a newer version of the FlatPak, I just thought that PureOS was linking me directly to the newest version. Thanks! I’ll try that and get back to y’all.
