I haven't honestly fixed the issue. But I know its not a Kissassist issue because it happens when kissassist isnt loaded.
Basicly when im using my SK and he has a pet summoned and isnt running kissassist, I will turn on attack and he will attack, when its time to send in the pet he will but it will turn off mq2melee and I have to reclick the attack button. If i send in the pet manually everything works as normal.
When im running the SK with a pet and with kissassist running he will never send in the pet.
Its not a huge issue to me because the SK's pet is really minimal dps and I was only useing it to level.
