[CLIENT] Lobby team chat not working

Just had a match where I kept asking who was going in what lane in the lobby and asked several times. Everyone in my party had all already had the "has entered room" message appear on my screen before I typed. After entering the match, I asked again and was like 'well I don't know where everyone is going, because noone would say anything in the lobby", but everyone confirmed that they were each talking, though several couldn't see each other, or me talk.
