HELP: Rotation Of Static Static Mesh Component Won't Replicate

I my BP I get the world location underneath the mouse cursor and I set the tank to look at that location each frame. I have set the tank to Replicate and I ran the set rotation on a Run On Server Only custom event. I have spent the last 3 weeks trying to find a solution. I will personally bake and mail cookies to the first person who fixes my problems.

The video is set to private. Could you set this to public? I need the solution cuz I’m facing the same problem ;(
