Lead graphic does not render correctly

When leads are used to attach animals at a fence, it won't render correctly after a while. it seems like a graphics glitch, but when several animals are attached to a fence, sometimes animals can get away from the fence they were attached.

 

Also, They don't appear correctly with wandering traders also. if traders roam through difficult terrain, leads will be stuck somewhere near(like trees). Llamas will still follow the trader, though.
