Unreal Engine 4.8.1 collision and shadow issues

2 problems I have found using UE 4.8.1.

First, when doing a component based Get Overlapping Actors and then going through the loop of the array from that node in blueprints for some reason it returns only the first overlapped component. Then the code after this loop node for some reason isn’t updated per tick when used with physics simulation. Hard to explain that, I’ll try to provide an example later.

Second, on an Android Device the shadows from directional light are mirrored along Y axis. Screenshots:
