As shown in this video, there are some pretty frustrating pathing issues in Kael Drakkel. I wanted to raise awareness especially to this case, where The Statue of Rallos Zek walked through a wall.

I also have noticed that in many cases NPCs will prefer to go straight down the middle of hallways, even when their targets are nearby, it's not uncommon to see them break off, run to a node in the middle of a hallway, path down the middle towards the target a bit, then re-engage.
