I get the impression lots of people on here are using software to spoil everyones fun.
I was thinking the same thing! I was about to make a move in my game and I get the results screen saying I had resigned. I was a newbie at the time so had no idea what had happened. Have not seen anything like it since.
Its not you. Its been a long term electrical problem called disconnect. There's been a lot of threads about it.
I don't have a resign hack.
But I have have seen an occasional hack resign.
