I cant explain this

Not sure what catagory this belongs in so please tell me if it’s in the wrong one.
So I’m not sure how to explain this but I made an fps game and I decided to test it on an alt and as I was walking, while shooting, I died on the alt account end but on my end, I was still alive walking around. The alt account end saw the character died and it stayed dead. I first came to the conclusion of a virus which I checked all my scripts and plugins so its not. It might be the gun and ray cast but I could really use an explanation for dying on one side yet still alive on the other.

Its because you’re damaging in a client script on a filter enabled game.
