This error keeps persisting, it an error started occuring after removing overlays from groups. Which was bugged in the first place as well.

Every us_road_asphalt_road_double I select creates this error, addtionally it creates a copy of that road for me to place down.

Since the last update I now get a new error

This error shows up on loading the project and everytime I select ANY road, even when I select a dirtpath.

I fixed it, there was one road with only 1 node, I added a addiotional node in the xml file, then deleted the road in the editor.
