Plutonium

Wanted to hijack this thread to say that even though both me and my friend have uPnP enabled (shoes up on network) and turned on in router settings, as well as being in the same house on the same network we are unable to join each other. Before the update my friend was able to join me through connecting to my ipv4 since we were in the same house but after this update we can't connect at all. Is this cause of the update or just because our computers can't utilize uPnP
