How do I get on a cruise whilst being offline? Silly I know I don't play LFS much nowdays

You cannot connect to any server if you are offline. Or do you mean play the whole track (open area) in offline mode?

If so, push ctrl at the track sellection page, then chose either the "X" or "Y" track to drive the open config.

Hope this helps

Also you can save layout from cruise server :

press SHIFT+U -> Save.

If you want cruise on offline go Multiplayer>Crate New Server and choose what you want

> cruise offline
> create new server

what?
