Playing as Lizard men, I had a dark elf army blocked in. One of my armies was in Ambush mode for 2 turns. I attacked a Dark elf army and they retreated right through my ambush army zone of control. without triggering the ambush.
Also... ( in pursuit of the waylay achievement.) ( win 5 ambush battles in a single campaign )
As Shaven i won at least ten ambush battles without earning the achievement. So I figured the attack % of ambush did not count toward the achievement.
However as lizard men I just won 5, without getting the achievement.
thank you for your time ..
