for his chat/hud message displaying info on how to use, it says that same thing for every new round you play, so lets say you start a new round, it says it, then once the round is over, and you go back to spawn, it spams it again for each players. so if theres 5 players on the map, it will say that 5 times on the server side chat. it basicly it spams.
hope that helps
