We played recently; at the start, I had version 3.52, and my opponent had 3.63. We both finished playing with the updated version 3.64. Both of us experienced a bug: in battle, neutral creatures didn't attack a stack that was within attack range (even if it could be killed with one hit), but instead moved forward. Since we were both playing as Inferno, it was unpleasant. I experienced this bug both before and after updating the version. Or is this not a bug? :)
