Pathing NPC's Chasing PC's Through Walls

[Little]

Currently, at least on the red99 server, mobs are not chasing there targets following the typical pathing. They are instead going through the walls in order to chase people down. This is resulting in enormous trains as a result.

It seems this most often happens when you are close to the target. If you nuke it from afar, it will sometimes do the standard route of pathing to where ever you are pulling the mob to. Body pulling seems to cause this pathing issue through the walls more constantly. That's my experience anyways.

This has happened to me in the following zones I have tested so far:

Nagafen's Lair
Lower Guk



Anyone else experience this more recently?
