[CLIENT] Can hear people leaving room long after I've left room

In the client, I keep hearing the little "whoop" sound that plays when people join/leave a room even if I left the room already. I'm 99.99...% sure that it is people leaving the chat room that I've already left, but the game just wants me to keep track of how many "whoops" I've heard so I know when the room is finally empty.

Peace!
