I've got news!
I have decided that this airport will not contain custom autogen. I'll probably make it later with much more quality and it will come in a separate pack, but we will have to wait. Custom autogen for the villages of Estarrona, Gereña, and Antezana de Foronda will be implemented anyways and the trees for the entire ortho area will remain too. The ortho area will remain the same, around 750 sq Km.
But this means good news, as the airport was already finished, this means it will be released soon. Beta testing will begin soon and as soon as it's done it will be released.
That's all for this post! More news about the release date soon!
