Tree textures don't applay until after firing projectiles

The majority of the time when I play my level in the editor the trees don’t render with their proper materials. For some reason after firing enough projectiles, they eventually change to the proper texture. Does anyone have any ideas as to what’s causing this?

I turned off several settings related to lighting and that fixed the issue. Specifically support stationary skylight, support low quality light map shader permutations, support point light whole scene shadows, and allow static lighting. Not sure why. I’ll post which one specifically it was after I go and turn them all on and off. Does anyone have any ideas as to why these lighting settings would cause this problem?

If anyone comes across this post with similar issues it was the sky light for me. Removing it or changing its mobility setting to movable or static fixed the problem. As well as changing the trees to stationary instead of static.
