When the host for a LAN game ends the session by clicking "Save and quit to title", the game then freezes and goes into "Not Responding", and then crashes. Don't know if this occurs on other operating systems, for I only have a Windows. I also noticed this only happens when there is more than one person on the LAN server and when they play for long periods of time.
Environment
OS: Windows 8.1 (Not sure if it occurs on other OS)
