Clients don't double check with server if it's the same staticobjects.con file.
They just assume it is.
So how can you move a static object in a file that's not given to your computer so it can render it?

Server doesn't render stuff, just tell your computer that you can move there, or can't move there.
The same way it tells you and your plane to go faster if it got more diff and torque.
Is it like 5 threads with the same thing in now?
Try it in a true test environment and come back with your results here.
A server with patchfile on it running a dedicated server.
You with a gaming puter without a patch connecting to server.
Run around and look. You see the things you added or moved?
