Bot's with Buggy Pets all of a sudden
 

r921:

Recently ALL pet classes pet's spam the message " That is not a legal target master ! " non stop even while guarding and nothing targeted . .can you please look into this and find out why. thanks !

I've seen this as well. From what I can tell by observation while testing, is that this occurs because the pet aggro'd something that is out of LOS and/or range. I believe this to be an artifact of npc warping/lag and not totally the fault of the bot code. A timer attached to a hate list whipe should fix this.

I am seeing this happen with client pets, too, for what it is worth.
