I'm an idiot. How do you save a LAN game and then reload it later with the same people? Thanks.

I play on a lan quite a lot. In my experience you can just save it like any normal game, but only the player who's hosting the game can do this!!

When you reload, load it from the multiplayer menu and from the PTW start screen. It will automatically put in all the former players.

Welcome to CFC and to me this question doesn't qualify you as an idiot (yet);)
