Root ghosting - mobs continue to walk towards me after root

[Awweshux]

On Blue: Ever since last patches, whilst root rotting (DL Rotting skel camp, CS bulthar camp, other places as well); once I have a mob rooted and dotted, when the root breaks and the mob starts towards me, if i root again, the mob keeps moving towards me even tho the root green cloud lands. Sometimes after a server tick or two the mob shows as rooted, but sometimes that root is not stuck and the mob wanders right over my head without hitting me and i root again and the root sticks on the mob behind me. Unstable root.
