Parkour Project Error in Rendering (Failed Renders + W.I.P. Render)

Despite everything looking fine in the Maya viewport and checking every keyframe, the Arnold Renderer is moving the eyes and hair along the animation while leaving the main body behind. I'm not sure why it would be doing this, as the hair and eyes are the same object as the rest of the model (?) and the animation shows up fine in the viewport. I'm assuming that the model was rigged wrong or that Maya has a problem with the model for some reason. 

The Parkour Animation was rendered in parts to be put together in Adobe Premiere. Below are the failed partial renders of the last two parts:
