Spells: Necro Pet Bug?

[Xaquin]

I suppose this may be game mechanics?

I'm currently a level 2 NE necro attempting to level in WFP. I cast cavorting bones and up pops my pet. We kill a few mobs and everything is dandy. I kill a decaying skeleton and all of a sudden my pet is gone.

I am at full health. My pet was at full health. A message pops up that says "kabobtik tries to hit himself. I'm sorry I failed you master".

Does anyone know what this is? I didn't have my pet targeted and even if I had, I certainly didn't tell him to attack anything. I was just looting a corpse.

This has happened about 10 times.

Is this normal? I was under the impression that the only thing (aside from dying to a mob) that could kill a pet was zoning or clicking the pet go away button.

Any help would be appreciated (my pets are poofing faster then I can get bone chips)
