I'm trying to run a Tekkit Legends server for me and my friend to play on. We're going through Hamachi, because my university doesn't allow me to port forward. We were playing for about 2 hours then both of us logged off, but I kept the server going. Now, every time I start it and have someone log in, it crashes and stops the server.
