Engines of War mission, after the ruins when you are coming down the hill towards the village end game sequence. There is a thatched fence that ends with a tree, then the path makes you make a hard left, almost 180 turn. Characters can get stuck in the area where the tree and fence meet because there is a rock that completes the “triangle” of terrain items there. You get stuck in the little area in the center. Enemies will approach but not attack you. You can spin, but cannot move or jump.
