The Necro Smasher's jigglebone is oriented the wrong way, causing the movements to be opposite of what you'd expect. The jigglebone also doesn't have a limit on its rotation, allowing the hinge to clip inside the hammer. Lastly, the Necro Smasher has no level of detail models, so whether it gets far away from the camera, or the model settings are set to medium or low, it still uses the same level of detail.

This submission fixes these things:
-Fixed the orientation of the Necro Smasher's jigglebone, and added constraints to its rotation
-Added LOD models for the Necro Smasher
