CoM mob pathing to corridor top when rooted

[sirelothar]

Hey. This started after the patch today and I wanted to report it. Basically you root any mob in a corridor and dot it and they will warp to the top of the corridor and you wont' be able to re-root or anythin since you cant see the mob, and in turn will bring a massive train. I included a video.. ignore the audio :)

Resolving due to age and multiple updates to pathing from patching.
