As a Roblox developer, it is currently too hard to stop exploiters from teleporting in our games w/client-based exploits, because GetPropertyChangedSignal won’t fire server-side w/the CFrame property when the client sets the cframe (And is in ownership of the part). I use this for detecting when players are teleporting around the map (Client pings the server), but they’re using exploits to intercept the remote signals being sent to the server.
If Roblox is able to address this issue, it would improve my development experience because it’ll stop teleport exploiters in their tracks immediately w/no way to bypass the detection.
