What happens is the player chooses the Morph (I know the Morphs aren't mine I was just testing) and it teleports then using there torso and when you get teleported you die

You are using R16. This means, there is no torso.
There is only UpperTorso
and BottomTorso
or like that.
Play the game and search in the explorer tab inside workspace for your character and then how these parts are called.
