I really need help with this animations issue I am currently having?

I have placed an animate script with a custom animation that I made into some NPCs and it works perfect in studio mode but online it doesn't work at all? The NPCs stand still for some reason.

I've been working on this problem for days, and I found a solution that worked for me! I assume it'll work for you too! It turns out that the animation has to played for each client that joins the game. This can be accomplished by using a loop or the PlayerAdded event. In the example code below, I use a loop.

AimAnimation = AnimationStorage:WaitForChild("Aim") --Wherever your animation is
local AimTrack = Humanoid:LoadAnimation(AimAnimation)

while true do
	AimTrack:Play()	
	wait(1)
end

As you can see, it takes very little code to run the animation! Hopefully this works for you.
