Animation with 1 keyframe works, whilst more then 1 doesn't

[m_acch (Mach)]

I have this animation I just made of a player being on a lockers counter,
I made one with it slightly moving and it doesn’t work (3 keyframes)

But when I load my normal one without any movements and just 1 keyframe it works.
What can I fix?

ServerScriptService handler script to put the dummy in the workspace

game.Players.PlayerAdded:Connect(function(plr)
	local dummy = game.ServerScriptService:WaitForChild("Dummy")
	local desc = game.Players:GetHumanoidDescriptionFromUserId(plr.UserId)
	local clone = dummy:Clone()

	clone.Parent = workspace
	clone:WaitForChild("Humanoid"):ApplyDescription(desc)
	wait(2)
	local anim = game.Workspace:WaitForChild("Dummy"):WaitForChild('Humanoid'):LoadAnimation(script:WaitForChild("Animation"))
	wait(1)
	anim:Play()
end)

It doesnt return any errors and the humanoid isn’t anchored

Have you set the animation to loop? I notice in your video that the animation didn’t loop when playing it in your editor and that might be a sign that you haven’t enabled looping for the animation. The animation probably finishes before you fully load into the game.

Oh right, I didnt realize that till I disabled my intro in replicatedfirst. Im trying to do anim.Looped = true in my script but .Looped wont show up or work.
