I`m also having lot of connection issues. Can´t connect to a game or when I enter I got "connection lost" all the time. And also a lot of my oponentes lost the connection too.
Sometimes me or my opponent get stuck in the mulligan screen, preventing us to continue, even when the count down come to cero. And can´t even exit the game while stuck, I have to Alt+F4.
I don`t know if it has anything to do with, but when I open GOG I got an update screen, that always ends in error. I try downloading directly from the GOG website but the version there is 1.2.31.8a and the version that I have installed is 1.2.32 so I can not install it
