How to fix this FE Gun Kit Error?

[retasdqwe]

So I’ve been using thienbao’s FE Gun Kit for quite a long time. But recently an interesting problem appeared. Why the ServerScript doesn’t even start?

That’s the particular part of code with which I noticed this problem:

local AnimationFolder = Instance.new("Folder")
AnimationFolder.Name = "AnimationFolder"
AnimationFolder.Parent = Tool
warn("i can't move it move it anymor") -- doesn't print out for some reason

Example of what happens right now and the error itself:

By the way the whole system works for other experiences I made. How can I fix this? Any help is appreciated!

So I found the problem. It’s not something with the gun script, but the function which gives the player weapons. The :Clone() thing was running on client and it needs to be on server.
