Well I saw that the president was himself the vice president, and even when I typed /intel in the chat it gives me the ip of the vice president in addition to that he was invisible in the map , and also he had the skin of the vice president + his weapons, and Vice-President class was not available.
This happened in the same map ( Los Santos ), the first one disconnected but there was still the bug
