DarkRP Lightsabers Not Working?

In DarkRP, I play on my own server. The problem is that the lightsabers from the lightsaber addon does not kill anything. It works only in sandbox. The lightsaber goes through the person without killing them. Is there a fix?

I am still really new to this facepunch and I do not know where this should go, sorry.

There are no lightsabers bundled with DarkRP.

I am talking about the lightsabers addon.

There are a dozen on just the workshop alone, this isn’t very specific.

Excuse me are you sure its the light sabers fault?
