Viewing castles is definitely a bug, and it might even make things fairer if it weren't there, but since it exists, let it be. And if it can't be tracked, then it should be allowed! I think using some kind of patch that disables bugs is a step in the wrong direction for the tournament. Let SOD be SOD!
I think each of us would gladly make some changes to the game, but you can't change the game in a way that pleases everyone! Therefore, playing in SOD is the only way out!
