Bug:
I was playing in LAN and a weird thought came to my mind. I changed my username to "Open" so when I enter other players' games, they will thought that "Yehay! I can now play LAN without any human opponents!". To test if it is ok to use that username, I made a new game. But I noticed something. The tab wherein you can see the other players who are also playing the game is FULLY EMPTY. Here is a pic.
Same happens with Closed. Don't do such.
