FoM causing intermittent game freezing when commanding pet attack

[uujfwmnp]

I was unable to find any kind of scripting error, but what I did find is that using FoM and telling my pet to attack, would make the game freeze for a moment. This happens every time I press the pet attack button, but only if I am out of combat. Once I am in combat, I can press the button all I want, and the game does not freeze.
