The routes created are no longer displayed in games. (but they do in the editor)
When you close the spline and reopen it, the route reappears in the editor, but that doesn't change anything in the game.
What's more, physics/collision with trees doesn't work any more, you just pass through them. If I create a new zone with the generator prefabs forest it works but after a random time the colision no longer works and neither does the route display.
If I publish the project on the workshop it doesn't work either, I always go through the trees and I no longer have the roads.
