Hello, Recently whenever I perform a server reboot certain chunks gets rolled back for many hours. Some chunks get rolled back around 30 minutes, while other chunks get rolled back multiple hours. There's an automatic /save-all to save the world running every 10 minutes, and also before every reboot, I make sure to do /save-all 3 times before the reboot starts. (a few minutes prior). I have checked all of the server logs, and there is no errors, or anything at all indicating this happening.
