Why does my Nexus have 0 health when he spawns?

I have a Nexus model that has health while it is in ReplicatedStorage. But after being cloned to Workspace, the Nexus has 0 health.

When it has just a Head part, it has health.

But upon adding a Torso part, it has 0 health.

Is there something wrong with my script?

local nexus = game.ReplicatedStorage.Nexus
local currentRound = 1

function spawnNexus()
    newNexus = nexus:Clone()
    newNexus:makeJoints()
    newNexus.Parent = game.Workspace
    newNexus.Humanoid.Health = (currentRound * 70) + 30
    newNexus.Humanoid.MaxHealth = newNexus.Humanoid.Health
    newNexus:makeJoints()
    newNexus:makeJoints()
    print(newNexus.Humanoid.Health)
    print(newNexus.Humanoid.MaxHealth)
end

wait(10)
spawnNexus()
