Sir, FE doesnt change anything...
FE prevents the client to replicate to the server. Your custom character most probably moves the robot through a LocalScript because the server doesn't replicate to the other clients that you are moving- for safety reasons! To get around this, use RemoteEvents and RemoteFunctions and link them up to a Script or turn of FE
