i got a problem that not been before
its just not playing animation like when i reload but it should and shooting problem that weapon have animation that plays but hands not moving(stuck on the idle animation)

i think problem with copying animations but i dont know reason and why this happens (i tried old version of game when this works normally but now its not)

here copy animation script

local char = game.Players.LocalPlayer.Character
local hum = char:WaitForChild("Humanoid")

if workspace.Fps:FindFirstChild("Arms") then
	workspace.Fps.Arms:Remove()
end

local fps = arms:Clone()
fps.Parent = workspace.Fps

local tracks = {}

runsrvc.Heartbeat:Connect(function()
	local currentPlayingTracks = {}
	for _, track in ipairs(hum:GetPlayingAnimationTracks()) do
		-- save tracks like in table index = animid, value = track
		currentPlayingTracks[track.Animation.AnimationId] = track
	end
	--for i,v in char:GetChildren() do
	--	if not table.find(added, v) then
	--		if v:IsA("Clothing") then
	--			table.insert(added, v)
	--			v:Clone().Parent = fps
	--		end
	--	end
	--end
	for anim, clonedTrack in pairs(tracks) do
		if not currentPlayingTracks[anim] and not clonedTrack.IsPlaying then
			clonedTrack:Stop()
			tracks[anim] = nil
		end
	end
	
	for _, originalTrack in pairs(currentPlayingTracks) do
		local anim = originalTrack.Animation.AnimationId
		if not tracks[anim] then -- create new track
			local newTrack = fps.Humanoid:LoadAnimation(originalTrack.Animation)
			tracks[anim] = newTrack
			newTrack.Looped = originalTrack.Looped
			newTrack.Priority = originalTrack.Priority
			newTrack.TimePosition = originalTrack.TimePosition
			newTrack:Play()
		else
			-- update params from original track
			local clonedTrack = tracks[anim]
			clonedTrack.Looped = originalTrack.Looped
			clonedTrack.Priority = originalTrack.Priority
			clonedTrack.TimePosition = originalTrack.TimePosition
			clonedTrack:AdjustWeight(originalTrack.WeightCurrent)
		end
	end
end)

If the animation is not uploaded onto your account or the group that OWNS the game (even if you own the group the game is in Roblox will not see it as the game’s) Roblox will think it is stolen and not load it.
I encounter this issue a lot when moving a game to a group

Game is on group and all animations
This should play properly it worked a 10-15 days ago I think Roblox make another update that breaks it
