I finally finished the fix. And added some new things. I hope that the map will no longer break and I don't need to do more updates. I've had enough, BeamNG editor it constantly buggy and crashed, and I lost my job.
1. Rally road (it will shake you suspension out)
2. Fix flying trees (but there are still many underground trees)
3. New Farm
4. New Bridge
5. Different road textures
There is still spawn bug, it totaly random and I cant repair it.
