I'm sure I'm missing something simple but haven't been able to find an answer for it. I setup a server using the AWS free tier so that our world would be persistent when any of my group of friends log off. I got everything running and connected last night. I realized today that when I close my SSH connection to the EC2 instance (just using putty) that it also shuts down the Terraria server. It's not difficult to get running again, but the point of doing this was so that we didn't have to have anything running on any of our local computers. Any help greatly appreciated!
