All fields are outlined with entry and exit paths.
All productions, buy points, sell points, and farms are laid out with markers for each point.
The only real issue I had was the grain elevator doors.
It's difficult to get a regular truck into the unloading area, and with a hopper-bottomed semi-trailer, it will be nearly impossible.
The ramp in and out of this area is too steep, and the doors don't help the situation at all, even with the automatic gate mod.
