Realm Cards, esp Address Cards, are lost when "Close Portal" is selected. I found this out the hard way when I just wanted to crackling noises to stop in my base. >.<
Closing a door doesn't normally mean you also locked it and threw away the key...
It would be nice to have "Close Portal" only close the portal (to stop the noise/music), while some other option resets it's realm connection WITH CONFIRMATION, like "Reset Portal" -> "Are you sure you want to reset this portal? If so, you will not get the realm card back and might not be able to return to the same realm. Yes/No"
