Even though I set :SetNetworkOwner to the player on the server, for some reason, midthrow, the server decides it wants to control the physics, causing the jittering motion. Any Ideas why this is happening?
There isn’t anything happening on the server-side code that changes anything related to the part’s physics.
So in this post someone talks about their code setting align orientation to nil and that error forcing server control on the instance.
But the error is not displayed, also I am worried your problem might be what the people at the end of this thread were talking about and not what the OP here ended up solving.
