Trees on rotator changing colors - a bug?

Thanks for the feedback!

Ok, now that I know there's nothing I can do to resolve the issue I can focus on some work around.

Unfortunately can't use the solution of the camera going around, as hard as I try the movement is very funky due to the poor camera controls (would be nice to have camera as an object and set it on a rotator with a pivot point on the center of the castle).

Will report this to the page you mentioned, thanks.
