This issue is in UE 4.X I have seen in it .7 through .11 and it is becoming disastrous. It is impossible to do lighting in space because of this issue.
Spotlights are off center at a distance.
The white line is from the center of the light to the center of the lit object with the light pointed directly at the lit object. Notice that the light reflection is up and to the left, up and to the left, up and to the left? The light reflection should be right where the line is on the sphere.
