How do I get a script being cloned to the workspace by the client to actually execute?

So filteringenabled is set to true and I have a local script in StarterGui that basically clones a part from ReplicatedStorage to the workspace next to the player's character and then that part disappears after set amount of time via a script inside said part. Interestingly enough, this works perfectly in the studio test mode, but in an actual server, all the parts get cloned to the workspace just fine, but the script inside the parts that are supposed to self destruct the parts are not executing at all; it's almost as if the scripts somehow don't exist at all?

I do not believe there is any problem with the local script, but I'm thinking perhaps there could be something wrong with script inside the part? I have no idea.

This is the self destructing script in the part being cloned:

local particle = script.Parent

for i = 0,1,0.1 do wait(0.05)
    particle.Transparency = i
    particle.PointLight.Brightness = particle.PointLight.Brightness - 1
end

particle:Destroy()

Again, this works perfectly in Studio mode, but not in an actual server, so I really don't understand what the issue is.
