R15 Npc Animation not playing. Help?

So I'm trying to animate an npc that is an exact copy of my player model, but for some reason it won't play in the actual game. It works fine in the studio test play. I've tried both local and server scripts. Any ideas?

The script is located in the model of the npc.

local Anim = Instance.new("Animation")
Anim.AnimationId = "rbxassetid://495426332"
local animTrack1 = script.Parent.Humanoid:LoadAnimation(Anim)
animTrack1:Play()

Try unachoring your npc model. May help.
