Noregs server issues?

Widow at half HP stands still, aiming at stuff, doesn’t notice me flanking. I shoot a helix rocket exactly at her. It goes right THROUGH her, exactly in the body center.
???
There was no movement or anything involved, she stood completely still. Crosshair was at the CENTER of her body and that was also where the rocket went (obviously).

In the last week I have had a surprising amount of noregs, although I have never seen a rocket noreg before, ever. What is going on with the server? This hasn’t happened before Season 4 really.
