First, I'd like to apologize.  It was late last night and I didn't think to try to save the replay or get a screen shot.

While playing on the Mines Map, as the forces of light, on the lower portion of the E, (Note the Orientation) No giants made it past the second tier of defenses.  They just faced the right set of defences and didn't move, no walking animations.  Either all giants got stuck or no additional giants spawned for the duration of the game as no giants ever made an appearance at the enemy base.  The enemy's gates were breached by the time they spawned but, their giants seemed to move normally.

I was the only demigod on the map.  I had captured the war idol.
