When a NPC attacks me, he can't touch other NPCs by accident

[Whaist]

Hi everyone!

 

I am looking for a mod or fix for, when 2 NPCs or more are attacking me (or anybody else), they can attack each other by accident (in case I dodge attack) or other NPCs they did not plan to attack.

 

You will see in the screenshot below, that the guard2 that is behind is trying to attack me and his weapon will pass through the guard1 who is in front of me and will touch me without hurting the guard1 as if he was a ghost.

Hope you see what I am trying to explain ^^ English isn't my native tongue.

Thanks in advance,

Have a good day.
