Can we save Apron?

Hi all, i need help, for my first scenery, i changed some ground texture grass with other grass from the game library (assobo grass under material) in SDK editor all is fine but when i save my projet + build and put my file in my community folder, in game all is good exept aprons i made, the ground is still satelite texture im confused,

but when i reload my project all is good, my apron back. very strange

What if you increase the priority level of the Apron? Also check the option “Force draw above runway”. Hope it helps.
