As tittle says some trees are missing textures.

[Quetzalkoatl]

Lauched game 2nd time and problem disappeared... I have no idea what caused that.

Although I have to say that in 2.5.3 1st mission load lasted like 3-4 minutes, in 2.5.4 it lasts 8-9 minutes with same graphic settings.

I guess it would need some optimization.
