[Fixed] Fixed a bug where Default group rewards were not given when signing in after enabling "Enable-Multi-Group-Reward" option in the Config.yml.
Note: As the above fixes have changed the functional logic, please check if the "Enable-Multi-Group-Reward" option in the Config.yml file is enabled before updating to this version. If enabled, it is necessary to evaluate whether the correct logic after repair affects the balance within your own minecraft server.
