I am making a game where you can make your own little mini games that are too small to be in the actual games tab of roblox, but not in my game. So I wanted to make it so that a client (with FE on) can delete someones place on their side when they are making it so they experience less lag in case they are doing anything that is laggy. But I want to know what would happen if like 5 clients have someone's place up and 1 client does not and a server script affects it. Would it make it pop back up for the one client who does not have it? Would it make the server script error? Heres what would make that.
--dis is a localscript if you could not tell.
workspace["hiimgoodpack's Place"]:Destroy()
Also, if a client doesnt have it but it pops up back for the client, would it get affected by a server script? Or would it just not be affected?
--another localscript
game:GetService('ReplicatedStorage')["hiimgoodpack's Place's Copy"]:Clone().Parent = workspace
Remember, Filtering Enabled is on.

And what if the client added the model back? Also, Inspect Element is not a chrome only feature
I didn't know if Firefox called it something else. If the client added the model back, the server wouldn't register it, so the server would still just be editing the original one. The server isn't going to start editing or be able to find the one you added back. This is where RemoteEvents/Functions come in to play. You use them to cross the client-server bounds.
