Hey all!
I think I noticed a bug, the “Get Hit Result Under Cursor by Channel” node does not work quite right after clicking in the game. Steps to reproduce:
-Program a top-down player to look at the mouse using that node described above
-The looking will work until clicked on the game, then will only work while left clicking or right clicking in the game
So apparently this has to do with the player controller settings, but im not getting much farther. I found this article, and the answer by GamerErrant actually is the first comment that relates to my problem.
Bump, still working hard to fix this 
Some player controller hide the curser pointer if you click the mouse to start yaw o pan views, like the third person controller. In this case use “set curser” to reactivate the curser after click event happend
