They found that objects outside of the cell boundaries in the z-direction could cause performance issues. This patcher cycles through all placed objects and all navmeshes. If it encounters anything with a z-coordinate less than -30,000, then it is placed at exactly -30,000. If it encounters anything with a z-coordinate > 30,000, then it is placed at exactly 30,000.
