What I'm trying to do is change the model to another without reloading character
(ux, uy, uz) are UpperTorso position of the default character
--titan
titan = titanModel:Clone()
titan.Parent = game.Workspace
titan.UpperTorso.Position = Vector3.new(ux, uy + 15, uz)
character.Humanoid.Parent = titan
localPlayer.Character = titan
--
I'm trying to solve this for an entire week, a there is no solution on internet :(

The Humanoid Instance details the state of the Rig it belongs to, detaching it will unfocus several significant aspects, ultimately causing "death" in this case.
