You totally just “saved” me a ton of troubleshooting royal force.
So just for a bit more clarity on the issue for anyone else with this problem. If you create a save game blueprint, then at any point after decide to rename your project, the old save game blueprint you created will no longer work. I’m assuming it keeps the directory of the previous project name, and the cast will fail because its no longer using the same file location. So my fix was to make new save game blueprints, and we’re back in business. Thanks again royal force
