Shooting an NPC will result in the server being ejected, and the following error message will appear.
Disconnected: RPC Error in OnProjectileAttack

Firstly, it should be noted that the server is genuine. After conducting multiple studies, I have found that a real teamID player who kills an NPC will be kicked out of the server. If the player receives an error message "Disconnect: RPC Error in OnProjectileAttack", the server's console will display the following error message:
Server Exception: Player Update
AssertionException: connection= Null
Assertion failure Value was null
Expected: Value was not null
