Pets not attacking

[Kiirani]

This is really frustrating, it seems in the last few days my pet has decided only to attack the enemy when it feels like it... I know that I can kill it with as many hp as I have, if I have both of us hitting it, and I know that if I can't, I run a few feet backwards and it starts hitting my pet (fighting ranged monsters at the moment)

Of course if it doesn't attack, not only am I hitting half as much as I expect, but if I run away, I keep getting hit until I'm out of range, it doesn't switch to my pet.. I have to run, sit, and finish it off.

Why have they suddenly started doing this?
