Can't find the problem

Hi guys, everything was alright until something happend on the editor and i have no idea what.
So i am making a game with an archer, the archer aims with the joystick.

The direction is the Blue dot minus the other Blue dot and other calculations.
But suddenly, it is not working anymore.
The blue dots has the same position (when i print it) even when i see they clearly don't.

Code (CSharp):

1.    Vector3 vectorToTarget = PointE.transform.position - PointC.transform.position;

vectorToTarget has always the same value.
What could happend in the editor???
I think i clicked Ctrl + Z and everything ruined somehow.
