Treyarch please fix this NOW. I was having a normal game of solo zombies on buried. I was leading leroy to the church so i could buy VA, but when he climbed over the rocks near the church, he somehow became stuck/frozen. He was not even doing that thing with his hands and mouth. He was not moving at all. This meant that i couldn't buy VA, pack a punch, or get him to help me by beating up zombies. Luckily though i had the jug place already open. I tried trample steaming him out, waiting a round, shooting him, none of these worked. I was too far into the game to want to start over.
Please trollarch. This is a major bug and it needs fixing.
