Why are you using the Offset Loft tool to create a road? This is not the proper way to create a road spline. You create road splines with the Spline Tool in Landscape Mode. Or alternatively you use a road spline blueprint and drag it by its node points. Also you have a pretty big knit in your tracks. You should even that out by the dragging the node up in the node height submenu.
This way my sidewalks or road borders will be lined up perfectly, but it doesnt seem to work anymore.
The Offset Loft tool is very buggy. I hardly can use it to place platforms and attach bumpers with it. For the first time I used the tool, I had a blueprint which worked to be placed with it but after a while it didn't work anymore and I can only use a handful of assets of blueprints with it. Not all. So, it happened to me too. But aside of that, rather use the Spline tool in Landscape mode to create roads. If you do it right, you can align it perfectly to the tracks as well.
You go into Landscape Mode, then there is submenu called "Splines". Click on in. Now if you rightclick and hold CRTL at the same in the viewport at any location, you create one spline control point. This is the start of the road. Now do the same another time, where you want the end of the road to be and it creates the spline control point for the end of it. Select the segment in between, and then assign a static mesh (not a blueprint) to the Landscape Static Mesh entry. Done. You can also see how it works in the video to this tutorial. The process illustrated there is for rivers, but it is exactly the same for streets and roads. The only difference is the static mesh you assign to the landscape spline segment, and the width you chose it to be. https://forums.dovetailgames.com/threads/water-river-tutorial.78261/
