A group effort can be an extremely productive thing, but right now the group you are in is becoming a quagmire of conflicting egos and hidden agendas. Be on the lookout for members of your group who are out for themselves. Don't get overly paranoid, just be sensitive to people who are too adamant about certain things. If someone isn't willing to compromise, then that someone is hiding something. Call them out before they steer things too far off the track.
