Control Rotation on Server

I’m having some really weird issues here and I genuinely am at a loss as to what to do. I am attempting to update the control rotation for a character. If I set it on the client, the server’s idea of what the control rotation obviously never changes. However, even if I do set it on the server the value never updates in the eyes of the server. I’ve monitored the value and it literally will not change after calling SetControlRotation. Does anyone know if there’s some sort of restriction for calling SetControlRotation in a server RPC?
