Painted foilage textures not applying correctly

Hi everyone I have been working on a simple side scroller project. I have been having problem with my painted foliage not showing textures. I have have about 200 speed tree meshes in the scene and certain trees display proper textures while others never load in. Inside the level I have exponential fog increased quite high and a large smoke effect. After having built the lighting and packaged the game it gives me the grey untextured base material. This can be replicated by using the standalone game option. This is using stand alone game, as you can see the trees are grey .

In the second picture you can see the textures applying when inside the editor. I have tried rebuilding lighting and different rigs. It makes no apparent difference. Please help.
Specs: GTX 960
i5 2400

240 gb ssd
If their is any other information that i can add please inform me.

This is happening to me as well but with assets from the Open World Demo Collection.

Still happens in 4.14. Having to redo the level as hand placed trees, not a big deal but annoying.
