You are not alone. This painted on reflections are driving me crazy too. If they are on the skin I take the textures into Photoshop and remove them. A lot of work because one has to to all the Make-Up files as well. If it is a free texture I delete it most of the time. Only a few were worth the trouble to repaint them. The eyes are really hopless. It is impossible to repair them.
Maybe we have to scream really, really loud to be heard. Leave the highlights to the lights pointing at the eyes and the skin. We can manage that. Can't we?
