Lost a 4 hour Twilight Imperium game because my neighbor moved his flagship through the wrong hex
We were 4 hours into a 6 player game at his place in Sacramento last Saturday when he moved his flagship 2 hexes instead of 1, and the whole table just let it happen. I didn't catch it until the next turn, and by then he had already wiped out my whole fleet and claimed Mecatol Rex. Do you guys call out illegal moves even when it kills the mood, or just let it slide and remember it forever?
