[EDIT] Animation fails to load in both studio and in game?

19:47:47.313 - Animation "https://assetdelivery.roblox.com/v1/asset?id=2078858298&serverplaceid=0" failed to load in "Animation.AnimationId": Animation failed to load

I'm currently trying to put animations into a gun system.

I own the animation. The game is published and I'm not using team create. The animation isn't being moderated as it's been sat around in my animations for a while now waiting to be used (months)

And it won't load. I'm unsure as to why and what's caused the error. I've tested this in both studio and in game and neither seem to work. Any help is appreciated.

[EDIT]

After a little bit of testing I found some even older animations (years older) reloading and crouching animations that do work in studio (not tested in game) I'd prefer to use my newer ones but these seem to work fine.

If anybody can shed some light on why this might be the case that would be brilliant.

server script

if Module.IdleAnimationID ~= nil or Module.DualEnabled then
	local IdleAnim = Instance.new("Animation",Tool)
	IdleAnim.Name = "IdleAnim"
	IdleAnim.AnimationId = "rbxassetid://"..(Module.DualEnabled and 53610688 or Module.IdleAnimationID)
end
if Module.FireAnimationID ~= nil then
	local FireAnim = Instance.new("Animation",Tool)
	FireAnim.Name = "FireAnim"
	FireAnim.AnimationId = "rbxassetid://"..Module.FireAnimationID
end
if Module.ReloadAnimationID ~= nil then
	local ReloadAnim = Instance.new("Animation",Tool)
	ReloadAnim.Name = "ReloadAnim"
	ReloadAnim.AnimationId = "rbxassetid://"..Module.ReloadAnimationID
end
if Module.ShotgunClipinAnimationID ~= nil then
	local ShotgunClipinAnim = Instance.new("Animation",Tool)
	ShotgunClipinAnim.Name = "ShotgunClipinAnim"
	ShotgunClipinAnim.AnimationId = "rbxassetid://"..Module.ShotgunClipinAnimationID
end
if Module.HoldDownAnimationID ~= nil then
	local HoldDownAnim = Instance.new("Animation",Tool)
	HoldDownAnim.Name = "HoldDownAnim"
	HoldDownAnim.AnimationId = "rbxassetid://"..Module.HoldDownAnimationID
end
if Module.EquippedAnimationID ~= nil then
	local EquippedAnim = Instance.new("Animation",Tool)
	EquippedAnim.Name = "EquippedAnim"
	EquippedAnim.AnimationId = "rbxassetid://"..Module.EquippedAnimationID
end

and local...

if Module.IdleAnimationID ~= nil or Module.DualEnabled then
	IdleAnim = Tool:WaitForChild("IdleAnim")
	IdleAnim = Humanoid:LoadAnimation(IdleAnim)
end
if Module.FireAnimationID ~= nil then
	FireAnim = Tool:WaitForChild("FireAnim")
	FireAnim = Humanoid:LoadAnimation(FireAnim)
end
if Module.ReloadAnimationID ~= nil then
	ReloadAnim = Tool:WaitForChild("ReloadAnim")
	ReloadAnim = Humanoid:LoadAnimation(ReloadAnim)
end
if Module.ShotgunClipinAnimationID ~= nil then
	ShotgunClipinAnim = Tool:WaitForChild("ShotgunClipinAnim")
	ShotgunClipinAnim = Humanoid:LoadAnimation(ShotgunClipinAnim)
end
if Module.HoldDownAnimationID ~= nil then
	HoldDownAnim = Tool:WaitForChild("HoldDownAnim")
	HoldDownAnim = Humanoid:LoadAnimation(HoldDownAnim)
end
if Module.EquippedAnimationID ~= nil then
	EquippedAnim = Tool:WaitForChild("EquippedAnim")
	EquippedAnim = Humanoid:LoadAnimation(EquippedAnim)
end

and one of the animation functions with a bunch of other stuff in it

function Reload()
	if Enabled and not Reloading and (Ammo > 0 or not Module.LimitedAmmoEnabled) and Mag < Module.AmmoPerMag then
		Reloading = true
		if AimDown then
			tweenNoAim:Play()
			--[[local GUI = game:GetService("Players").LocalPlayer.PlayerGui:FindFirstChild("ZoomGui")
			if GUI then GUI:Destroy() end]]
			GUI.Scope.Visible = false
			game:GetService("Players").LocalPlayer.CameraMode = Enum.CameraMode.Classic
			UserInputService.MouseDeltaSensitivity = InitialSensitivity
			AimDown = false
			Mouse.Icon = "rbxassetid://"..Module.MouseIconID
		end
		UpdateGUI()
		if Module.ShotgunReload then
			for i = 1,(Module.AmmoPerMag - Mag) do
				if ShotgunClipinAnim then ShotgunClipinAnim:Play(nil,nil,Module.ShotgunClipinAnimationSpeed) end
				Handle.ShotgunClipin:Play()
				wait(Module.ShellClipinSpeed)
			end
		end
		if ReloadAnim then ReloadAnim:Play(nil,nil,Module.ReloadAnimationSpeed) end
		Handle.ReloadSound:Play()
		wait(Module.ReloadTime)
		if Module.LimitedAmmoEnabled then
		local ammoToUse = math.min(Module.AmmoPerMag - Mag, Ammo)
		Mag = Mag + ammoToUse
		Ammo = Ammo - ammoToUse
		else
	    Mag = Module.AmmoPerMag
		end
		ChangeMagAndAmmo:FireServer(Mag,Ammo)
		Reloading = false
		UpdateGUI()
	end
end

In the module script it looks like so

	MouseIconID = "316279304";
	IdleAnimationID = nil; --Set to "nil" if you don't want to animate
	IdleAnimationSpeed = 1;
	FireAnimationID = nil; --Set to "nil" if you don't want to animate
	FireAnimationSpeed = 5;
	ReloadAnimationID = nil; --Set to "nil" if you don't want to animate
	ReloadAnimationSpeed = 0.5;
	EquippedAnimationID = nil; --Set to "nil" if you don't want to animate
	EquippedAnimationSpeed = 1;

I have left out a bunch of other repeated animation functions if you need them as well though just ask I've left all of the current animations as nil just for simplicity's sake.
