Since the rule has been made noone has flipped the table… Yet.
It was flipped once after turn 3 of are second game of global.
I was Italy and taking over a poorly played Japan from a friend who had to go. The Allies were going really hard on the Pacific and after my turn 3 which was extremely good especially with dice rolls. They took there turns and flipped the table as they saw the writing on the wall. That is why the rule was in place.
