I have a GameObject on scene, let's call it DogObj. The DogObj is deactivated in the scene. When I play Timeline that uses Activation Track with DogObj my additively loaded scenes are unloaded. Then when DogObj is activated they are loaded and after active period are unloaded again. When Timeline finishes playing scenes are loaded again and DogObj is inactive like in the beginnig. DogObj doesn't have any scripts attached nor is referenced by anything with the exception on Timeline. I'm using Unity 2017.2. Is there a workaround? Maybe someone has implementation for a custom activation track? It would be nice to have active by default activation track.
