ClientCast - A Client-based, Idiosyncratic Hitbox System!

[Downrest (Down)]

Hey there!

So I’ve been using your module to make a sword system. Works pretty nice, however I noticed one thing.

Whenever I try to set the owner of the sword and do Caster:GetOwner(), it prints out nil? And using Caster:GetPing() prints out 0.

Did I mess something up?
