Not saved in asset editor

[Machine-Maker]

This is assuming networks are supposed to be saved while making an intersection in the asset editor

A road (highway ramp in this case) is not saving without streetlamps.

I place some road w/o street lamps, save, and then reload, and the road then contains street lamps.

intersection support (or in general, asset editor support) is possible, but quite a huge task.
