We are implementing automatic reboots on all regions over the grid. Each region will reboot every 24 hours. if you wish to have your region reboot the same time each day, Pick a time of day and reboot your region from region estate this will start the 24 hour countdown.
If you do not wish to have your region Automatically Rebooted please send a support ticket to support@aviworlds.com
This will help keep everything running smooth and give you all a better in-world experience.
