I have been trying to edit a map for myself and had to rearrange some roads. When I finished, the roads weren't drivable. They weren't solid. Everything to my knowledge was normal. I compared it to other roads and all the properties were the same. Here is a video for demonstration:
I think it's because when you move the static objects, you don't actually move their collision box as well, so you need to update their collision box position. Try running this command in the Lua console be:reloadStaticCollision(false)
Once you have everything where you want it, simply restart the game and the collisions should work again.
