New Gaia user here. How do you save a new Gaia project? Built the first demo, went fine, generated it out to a windows 32 bit build. saved scenes, saved project, exited Unity. Reopened the project the next day to build a 64 bit test for comparison and the project opens, with the GAIA menu window still open, but the scene has only the original camera and directional light. What did I miss? I explicitly saved scene and project before I did the windows export.
