Game Mechanics: Pets Disappearing / Pet Guard

[Aelzrith]

Recently, when a pet is guarding somewhere, after it kills a mob and returns back to his guard spot, he'll wander off and aggro mobs. This killed me twice in Sebilis tonight.

Since the last patch, I also see that pets are warping through walls - I've seen this mostly in Seb when running around corners and a pet is following closely behind. It's like they don't follow the nodes and follow the PC too closely and disregard walls. Then they warp up or down the Z axis...
