Server crash or reboot without warning very regularly between 9-11pm ET. Then because there were no saves within the last 30min (to an hr sometimes), everyone looses all there work. This has been happening almost daily recently. It wouldnt be as much of an issue if there were more frequent autosaves, but the user unfortunately has no control over how often autosaves occur. 

If these crashes/reboots happen multiple times within the hour, you can find yourself in a loop where you continually reset to the same point and never accomplish anything. 

This isnt a local internet connection issue since it boots everyone connected to the server and we regularly have 3-5 people from across the USA on the server and they all get disconnected.
