I just built a rather large setpiece for my game that should be accessible at certain times. Loading the scene is fine, the file is great but during scene changes I am getting a "null pointer" error and I am having tried abstracting, loading and preloading the scene to no avail whatsoever. Help is appreciated. I am on the most stable/recent branch of Godot 3.5. My scene is supposed to change after a small animation in instanced and resolves.
