no, I know the incident he was talking about. The zombies were already on the inside of his "cade" on the two towers. I threw a nade which blasted 2 zombies off from killing him. The spot he was in was one that the zombies can get into by pressing E and making the "objects" pass throughable. I do understand how he can think that I did break his cade, but it was already broken in by the zombies on both ladders.
