The frequency of server saves is dependent on how long the server has been online.
For the first 24 hours after the server has been restarted, server saves will occur every 15 minutes, maintaining the standard save interval. Once the server has been online for 1 day or more, the save interval is extended to every 30 minutes. If the server remains online for 3 days or more, server saves will occur once every 60 minutes.
This system helps to optimize performance while ensuring player data is securely saved at regular intervals.
