Bigger maps are not being rendered

Hi!
First of all thank you for your excellent work, the project is really impressive!

I'm trying to create a map of my own which is quite large, below is the visualization of lane surface:

When I try to use it inside the simulator I get an issue that at some point the road dissapears below the grass surface:

In top down mode everything looks fine (I reached the second intersection)

Do you have any suggestion what could be the problem and how can I fix it?
Thanks!

It was fixed in the latest PR. The max map size is 4096m * 4096m
