Yesterday, I transferred a world from this computer to my other computer, and renamed it (from Life V2 to Life V2.1). I connected to the world from the second computer, and made a LAN server for my friend to join from this computer. Today, when I tried to transfer the world back from that computer to this computer, I renamed it to Life V2.2 and tried to enter it. "Server closed" popped up for a split second, and then the game crashed. I looked around the forums and I think this has to do with it being a LAN and connecting to it from a different computer. But I am connecting to it with the same account... Please advise. Thank you.
