So you know, fix one problem create another... Now I can't figure out why my turn will not end, and it turns out I have a caravan sitting in what appears to be the tile of another city, only it isn't apparantly legal for it to form a route, so it is just there. And since TAB doensn't find it, have to hunt and peck around map to find why turn isn't ending. There needs to be a difference in the game between caravans that have established routes and ones that have not.
