The test server is up with a light version of a future limited time mode: code name "Challenger Throwback", if you would like to explore and provide feedback that would be great! The only zone populated with NPCs at this time is Ratling Run. We will continue to populate zones and tweak mana cost over the next few days.
Amazon is having issues with their S3 service which causing the launcher to hang on loading the feed list. The work around for this time is to navigate manually to game directory and launch the game: C:\program files (x86)\rat labs\the realm online\FF
For now keep on eye on the AWS service to return and then the launcher should function normally. You can monitor it here: https://downdetector.com/status/aws-amazon-web-services/
Sorry for any inconvenience and we’re working a solution for future issues.
