Black Tree's in Nek just outlined help!
 

While in Nek forest today I decided to update my UI, and now everytime I come near any tree the image loses it's colour and just shows the black outline of a tree, i'm not sure whats the matter if anyone could help would be greatly appreciated.

It sounds like you got your night vision on. That's the good little feature of profit. Locate the toggle button for this on the Start button panel. :)
