Hello, I just downloaded your modpack after a friend recommended it to me. We are thinking of starting a server with you guys soon. I seem to be the only person having this problem when i play by myself on a single player world. Sometimes I will be in the middle of a random event happening, I.E taking some items out of a furnace or vein mining some gravel, and the game will freeze, shut down and say Shutting down Internal Server. What does this mean, and how can I fix it?
