Can't move object when setting rotation in construction script

When setting the rotation (SetRelativeRotation/SetWorldRotation) on a child actor from the construction script, I’m not able to move that actor in the editor. See images for more info.

I am not entirely sure, but i think you need to get actor location and not world location. I might be wrong.

That gives the error child actor component reference is not compatible with actor reference when I try to do that with the light. I need to get the location of the light, not the location of the whole actor to be able to find the correct look at rotation

I have the same issue in 4.11 to do the exact same thing.

The object gets updated within the blueprint´s viewport, but no tin the scene
