If you try to start the game during maintenance, you will see a message inviting you to connect later.
This means that we do what is necessary to provide the best possible gaming experience. Don't worry, Captain, your boat is still sailing as instructed. It does not stop during maintenance.
You will be able to take control again once maintenance is complete.
Maintenance can be carried out at any time. As anticipation is a sailor's own thing, we recommend that you use the navigation instruments available in game to plan your route for the next hours.
