A player is able to see some players but cant see some other players. Also a player who is invisible might become visible due to dying or changing avatar character. The player just isn’t able to see the other players character but that’s it, I tested by attaching a part to the character.
I have a feeling its because of this warning:
RunService:UnbindFromRenderStep removed different functions with same reference name utility-focus-state-friendstatuslabel-MATHEUS_xham 2 times.
