I don't know if this happens for everyone, but for me, when a room closes down, I cannot communicate in the private chat I had with a partner (or anyone else) anymore. I ask if they are still there but I get no response, meaning my message probably doesn't get through to them. When a room closes, it would be very nice to be able to continue the private chat with my partner (or other), so we can at least communicate which open room we would like to join and continue. On a tangent, sometimes I am unable to join a new room after the old one closes: the loading screen lasts forever and I have to restart the game in order to be able to join another room.
