Ghosting mobs

[BarackObooma]

This happens quite a bit. I'll have a mob rooted, it will break root and start coming towards me, I'll root it again and get a success message but the ghost of the mob will keep walking towards me until it goes past me and then the rooted mob is invisible until I move around.

If you land a root and the mob keeps ghosting toward you, you can move a tiny bit and the mob will appear in its true location.
