Slag Trigger Disappears

[tootallll]

Sometimes my pet trigger disappears and i cannot trigger my pet...only happens when using Slag. When I switch to another pet the trigger comes back.

There was an update with skills and pets, that after you pressed the skill or the aa, the pet and the skill can not be switched until cool down is finished. This prevents exploitation of buffs by pets, and more than 4 skills.
