Box Line Trace / Get Centered Impact Point

Hi guys!

I’m working on a ledge climbing system.
It worked. But now it doesn’t work anymore because why not (I only saved/reopened).

The problem now is, that the Box Trace for the Wall doesn’t return the Centered Impact point of the box.

I NEED to use the Box Trace, because I want to have angled walls, too.
Sphere/Capsule Traces only return the center of the Sphere/Capsule when hitting the wall.

Does someone have a solution for this?
