1) PlayerOne invites PlayerTwo
2) PlayerOne waits till PlayerTwo has joined the group
3) PlayerOne invites PlayerTwo again:
→ Group_Invite_Response_Already_Grouped - inviterName=[PlayerTwo] inviterDisplayName=[] - GetGroupSize=[2]
4) PlayerTwo logs out to Char Select Screen:
→ EVENT_GROUP_MEMBER_CONNECTED_STATUS - unitTag=[group2] PlayerName=[PlayerTwo] isOnline=[false] - GetGroupSize=[2]
