I am trying to run Superpowers on a headless server. I followed the steps in the Setting up Superpowers: Download Superpowers-Core and unzip it. Then in the terminal type "node server start". The server starts and I managed to login, but I try to create a project I get the error "This server doesn't have any systems installed yet. Please install one from the Server Settings tab first". I've tried to download the Superpowers-Game and unzip it in the "systems" folder in the the Superpowers-Core directory, but that did not work. I am using Ubuntu and Superpowers-Core-v4. What should I do?
Edit: I cannot see the server settings tab mentioned in the error. Is there something wrong?
